After awakening in the past, Robb immediately goes and hugs all his younger siblings: Sansa rolls her eyes, Arya reddens with anger and Bran and Rickon outright squirm to flee their brother.
In chapter 4, when Robb is telling Ned how much King Robert let himself go during the past years, he mentioned how when he arrived Winterfell he pretty much fornicated with half of the whores there:
In Chapter 28, After arriving at Storm's End, Robert catches a septon trying to stomp on a weirwood sapling and gives him a beating. Even he has to note the absurdity of the statement.
"You leave Lyanna's fucking tree alone!"
Jon Arryn refuses to give Janos Slynt the option of the Wall, on the grounds that "he might try and sell it to the Wildlings."
From Chapter 51:
Robert: Jon? Jon Arryn: Yes Your Grace? Robert: Why is the head of my Master of Coin looking down at me from a spike?
Upon awakening in Chapter 52, Willas Tyrell finds out from his grandmother that he had twice woke up as Mern IX, the last Gardener king, bellowing orders to people long since dead, and collapsing. Oh, and he pinched the bottom of the maid who brought him his food. Twice.
Olenna: With hindsight, it was all most amusing.
When Olenna tries to deny being worried about Willas, even after a Maester's prognosis, Margarey shows her brother the embroidery that their grandmother a.k.a. the Queen of Thorns had made: a Maester being chased by a thorn bush.
And when Willas meets the maid in question – or at least he assumes so, from how she's blushing – he compliments his other self's good taste.
Several people – such as Alliser Thorne – mention being on the privy when they heard the Call and nearly shitting themselves as a result.
Arya races in to give a rapid-fire talk on how the Old Gods spoke through Jon, only briefly interrupted – twice – by her mother reprimanding her for calling Tyrion an imp.
Tyrion: I am most impressed, Lord Stark, by your daughter's ability to say all that without apparently breathing at any point.
Having been travelling together, Brynden and Brienne meet the Green Man who offhand comments to Brynden on Brienne being "your wife." The two assume it's a mix-up and insist they're not married... only for the Green Man to go "oh, sorry, bloody tenses."
Just the idea of the Blackfish and the Maid of Tarth as husband and wife is hysterical.
The Green Man then turns to a tree and tells it to stop laughing at him. In fact, he keeps arguing with it the entire time... with Brienne and Brynden looking more and more confused since they can hear only half of the conversation.
Brynden's vision is both a Green Man passing down mystical revelations, and an uncle chatting with his nephew; Edmyn Tully is annoyed to discover that Aegon was lying about being able to produce Valyrian steel.
Edmyn: Shit. I was promised a sword. The Green Man: You'll not get it.
Chapter 85 has Olenna in fine form tearing into Mace for his plans to marry Margaery off to Robert.
Olenna: I admit it——I gave birth to an idiot.
In Chapter 88, it is revealed that Jon Arryn had a new candidate in mind for the Master of Coin position – Lord Stoutheart, who upon hearing of his nomination, was so happy that he promptly dropped dead of aheart attack.
In the same scene, Renly comments on what Jon Arryn's title is now that Stannis had been made Hand of the King, but passed his duties back to Jon while he and Robert are in Winterfell.
Renly: I am still a little unsure as what your title is, Jon. Acting Hand? Temporary Hand? Second-Hand?
Also in Chapter 88, Lord Hoster Tully requests his son Edmure to find a wife to continue the Tully line. Edmure agrees on one condition:
Edmure Tully: Please – no Freys.
Chapter 90 has Doran Martell express great annoyance; following the advice of a Maester that Oberyn recommended, of cutting down on certain foods, his gout has lessened to the point that he is now able to walk again for the first time in a long time. So why is he annoyed?
Doran Martell: Because all the things I should not eat are the things that I truly love to eat!
Lady Catelyn comparing the usually grim-faced Jory Cassel to a poleaxed ox as he is about to get married.
Rickon apparently had to come up with a few other names for his direwolf before settling on Fleetfoot. Other possible names were Smellypoop, Big Paw and Ouchyfinger (the pup bit him).
Arya is trying to get Nymeria to look at her to try and warg into her, but the pup is far more interested in the lamb chop Arya is eating. Even when Arya puts the lamb chop in front of her face, Nymeria ignores her.
And later on when Arya is dreaming and the Old Gods speak to her. The Old Gods are shown as powerful beyond measure, and they simply sigh and laugh at Arya speaking to them.
When hearing that the royal family would be riding all the way from White Harbor to Winterfell, Cersei tries to get a wheelhouse made for the trip. Given the speed that Robert wants, the terrain, and the number of times they'd have to change the wheels, all she gets is Robert laughing himself to tears at the sheer impracticality.
Robb, Jon and Theon all end up staring at Mance Rayder's goodsister Val when they see her. "Yearning" is the word Ned uses to describe them.
In Chapter 101, Gerion Lannister arrives to the Nightfort and reveals himself to his nephew Tyrion, who has thought the man dead for nearly a decade, and naturally faints at the shock and falls off his horse. Luckily Gerion catches him.
Gerion: Why, Tyrion! Hello there! Tyrion:[Squeaky] Uncle Gerion? Gerion: Well-met! Interesting company you came with. Tyrion:[Still squeaky] Uncle Gerion? Gerion: Yes. Are you alright, boy? Tyrion:[Flatly] Uncle Gerion. Gerion:[As if to a child] Yes. It's me. Your uncle Gerion. Tyrion: Uncle Gerion. [Faints] Gerion: Well, I think he missed me.
Gerion cheerfully admits he has sex with his wife, a lot, in front of his dismayed son. Mance Rayder and Tormund feel No Sympathy whatsoever for the lad – those kneelers sure have strange hang-ups about life, eh?
After word gets out in the Reach that Willas's leg has been healed and that he has claimed Otherbane, the Ancestral Weapon of the Gardener Kings, a lot of noble houses in the Reach (that had previously ignored him) have been sending him marriage proposals for sisters and daughters of all kinds. Grandmother Olenna's usual acerbic commentary about the offers have left Willas in stitches.
Walder Frey suffers multiple ignominies when the Green Men reach the Twins, with Ser Duncan the Tall even telling him that he has not changed much from the snotty-nosed little brat he was when they met more than 80 years before. Then Yoren shows up with a wight's head, which makes him suffer a stroke at the sight of it. His bladder then empties, and the Late Lord Frey is left dying, sitting in a puddle of his own urine, all while his numerous descendants freak out.
In reaction to the above, one of the commenters imagined a revised letter of condolence from Jon Arryn to Stevron Frey that was drafted so long ago Jon was still married to his cousin Rowena.
Arya thinks about one of her warging attempts with Nymeria, where after she did so, Frostfyre amusedly and bemusedly licked her all over, as if knowing perfectly well what Arya is doing with her pup.
Willem Bootle, saying he is not afraid of legends and heathen symbols, swears an oath of innocence on the Fist of Winter, and he promptly dies when the magic in the Fist punishes him.
Robert finally arrives to Winterfell, and he and Eddard confront each other about their new signature weapons.
Robert Baratheon: Nice stick. Almost as good as my old warhammer. Eddard Stark: Nice knife. Almost as good as my old sword. (Beat, then Robert and Eddard start laughing as they embrace each other.)
Joffrey is mentioned as preening as he catches sight of Sansa, sending her what he thinks is a charming smile. Sansa does not even seem to notice him.
When Robert greets Catelyn, he also ruffles Rickon's hair. Rickon is visibly thinking of biting him.
Renly insists on calling the reduced Small Council "the Smaller Council".
A meta one: On the AH.com thread, the decapitated wight head that is one of the parts the Night's Watch has been taking around Westeros to prove that the Others have returned was nicknamed Dame Head-rot, with the joke being that it was the new Master of Coin. Guess which part is presented to the Small Council?
While Gendry is in Winterfell's forge, Shireen brings the Terrible Threesome to meet him – and promptly demonstrates she's got them under control.
With Sansa being betrothed to Joffrey off the table, Robert suggests betrothing Arya to Tommen instead. Once Ned tells him that his younger daughter is the second coming of Lyanna, and comparing her to his Kindhearted Cat Lover son, Robert isn't so sure.
Robert:(dazedly) The poor lad.
An off-hand one in Chapter 117. King Robert is preparing to do something with Stormbreaker to prove his children's paternity. All of his children are in the room, watching him do this, including Joffrey. Who is giving the sword what can only be described as a look. This prompts Robert to say "It's just Stormbreaker, Joffrey, it's not going to bloody bite you." Little does Robert know, in Chapter 86, that actually HAPPENED.
Ned's plan to expose the Lannister twins is by blatantly catching them in the act with multiple and highly reliable character witnesses (himself, Stannis and Barristan) in a manner that makes it impossible to deny or cover it up............and Cersei still tries to claim it's all lies. The sheer audacity of it actually causes Ned to burst out laughing.
During supper right before Tyrion comes in to tell him about Jaime's decision, Ned takes the last piece of bread just as Rickon was going to reach for it. When his son looks at him in shock, Ned sticks his tongue at him and tousles his hair, then gives him the bread anyway.
Tyrion belatedly remembers two of his Lannister cousins (who have made no appearance in the story thus far, despite being Robert's squires):
Dacey: Have any of your family, other than your siblings, been placed in a cell or asked to leave? Tyrion: Well… no. I'd forgotten Tyrek was here. And Lancel. Haven't even seen either of them.
In-Universe, Oberyn Martell excuses himself to laugh himself to tears when he hears that the Lannister twins had been caught in the act and arrested in Winterfell.
Then, when Pycelle tries to argue that Eddard, Stannis and Ser Barristan may have misinterpreted what might have been innocent horseplay, Oberyn again laughs until he's out of breath, before pointing out how absurd that is.
Oberyn Martell:Of course, Maester Pycelle. Based on the latest raven from Winterfell they innocently both stripped naked and then she somehow fell onto his erect cock repeatedly. How could that possibly be misinterpreted?
And since this was all done in front of Robb and Theon, both of them quickly go from Corpsing to tear-faced hysterics, especially when Jon throws back an "I Heard That!" to their laughter.
It's heavily implied that Septa Mordane has done something to greatly annoy Eddard since every time her name is mentioned, Ned flares his nostrils which Sansa says is never a good thing.
When word reaches the Tyrells of Jaime and Cersei's incest and Robert now being single, they are naturally stunned. Of course, Olenna has to respond first by noting that if Mace was still alive, he'd be pushing Margaery into Robert's arms. "How the Old Lion must be raging!"
In response to Kevan's shock at him being alive, Gerion bets him a silver stag that Tywin's first reaction will be a simple statement of “You’re alive” and then to ask him if he found Brightroar. A few minutes later, Kevan has to hand over a stag.
After Tywin wonderfully summarizes the entire story so far in one long-winded speech... he can only sit and laugh at the fact that of all his children, Tyrion turned out to be the noblest and bravest of the bunch.
While we don't see it, Tywin mentioning that he backhanded Joffrey.
Just the fact that Cersei is unable to get out one word to her father while Tywin verbally tears her apart for her actions.
Some Black Comedy bits in the speech include Tywin snapping on how, somewhere in the various Hells, Aerys Targaryen is looking up and laughing at him.
Maester Cressen privately refers to Baelor the Blessed as Baelor the Cracked.
Sam spends so much time in the library that he barely takes the time to eat, so he has invented something to make it faster: the sandwich. Which the cooks and maesters like so much they are starting to call them "Samwells".
The Green Man taking Sandor Clegane by the ear to drag him in front of the weirwood. An onlooking Domeric Bolton balances between confusion and hilarity.
Ygritte insisting on coming along with Jon on the mission to the Iron Islands, to his frustration and Robb and Theon's amusement.
Oberyn expresses his desire to meet with one of the Green Men, which he has tried (and failed) to do before. When a Green Man appears in King's Landing to plant a weirwood in the Red Keep...
When Sarella reads a letter from her father Oberyn telling her that he is sailing northward with barges of (hopefully) inert wildfire and that the King has been informed, she imagines Robert Baratheon's reaction to be something like, "The balls on that man!"
Robert is a Shipper on Deck for Jon and Ygritte, primarily because he's amused by how the thought of the Mad King's only living grandchild marrying a Wildling would have enraged Aerys.
When Ygritte learns about Jon joining Ned to check on the fog, she starts ranting. Asha tells her to go get herself a room with Jon when he comes back and tell him what she feels. Ygritte blushes as red as her hair.
Then, when Jon comes back and she asks why he never said a thing, Jon points out he was the only one that could accompany Ned, and that she would have had to wait with the direwolves. Ygritte (after a slight push from Asha) gives him a big kiss, then slaps him in the face and leaves, with poor Jon completely flabbergasted.
For a bit of Black Comedy — Davos and Oberyn tell Jon Arryn of a clearly mad septon who tried to make his way onto the ships containing the wildfire, bluntly telling the guards that he intends to detonate it in order to burn all the heretics in King's Landing. When they turned him away, he declared that the Seven would allow him to walk across the ocean to Andalos and receive their blessings. According to Davos and Oberyn, he was found floating face down in the water not long after.
Robb reflects on how some Northern lords are pushing for him to wed Margarey Tyrell in order to tie the North to the Reach's bountiful harvests.
He'd never met the girl, but a lot of people talked of bounteous harvests a great deal when they spoke of her, so it might have also been a reference to her chest. He wasn't sure.
"You fucking great idiot. That's the wrong bloody Stark."
In this interpretation, The Mountain's genuine amusement before his death just adds to the Black Comedy in the moment, almost as if Gregor himself was basically laughing at the fact there was someone more stupid than he was.
Sea travel does not agree with Ygritte. Jon goes to comfort her in spite of her threatening to gouge his eyes out, reasoning that she's far too wobbly to aim the knife right to him.
While tearing apart the prophecy that Maggy the Frog gave her, Tyrion explains to Cersei that "Valonqar" also refers to a Myrish chest ailment and a Braavosi pastry, and that she might have actually misheard the word "Valongar'', which is a type of fish dish. Cersei, understandably, is dumbfounded by all this.
Tyrion's entire conversation with Cersei has a strong undercurrent of "You couldn't even get THIS right?"
After Tyrion leaves, his sister starts screaming insults at him through the door. The attending guards just jape about her "piss-poor use of insults".
The fact it honestly never occurred to Cersei that the brother she spent the most time around would be the one that got her in trouble, instead of the one she rarely saw, is giggle-worthy in a Black Comedy way.
Asha's reaction to her nuncle Rodrick announcing his wife is pregnant: "Nuncle, you old dog!"
As Cersei is finally being taken off to exile, she spots the Hound and demands that he help her escape. His response? "All hail the Queen of Nothing!"
Just the mere fact Cersei is so deluded that she believes that she's the still the Queen is hilarious in of itself.
As Shireen berates the Fearsome Foursome for thinking a dragon could lay eggs in the godswood's pond without destroying the trees and enraging the Starks, Ned suggests the dragon could have flown over the godswood, aimed for the pond and shot the eggs.
Jaime confesses to something: he once pissed on a weirwood.
When a minor lord named Piglott comes before the Iron Throne, Renly has to keep reminding himself that the man's name isn't Piglet.
After his epic battle with the Drowned God, Ned tiredly says that he needs some ale.
King Robert Baratheon and Maester Aemon laughing at the knowledge of Jon Snow’s Relationship Upgrade with Wildling girl Ygrite, especially that Mad King Aerys II Targaryen is probably screaming in rage and frustration, somewhere in Seven Hells.
imagined a revised letter of condolence from Jon Arryn to Stevron Frey that was drafted so long ago Jon was still married to his cousin Rowena.
