* In the season 6 premiere, Dennis tells Mac that he hasn't had feelings since he was 14 years old. Come season 11, we find out that Dennis was statutory raped by a fifty-year old librarian when he was fourteen

* In "Being Frank" it's revealed that Frank has an unknown terminal illness, but it isn't treated because Frank runs out of the hospital in a hurry. In "The Gang Goes to a Water Park" Frank pretends to have [=AIDs=] in order to get onto all the rides. This culminates in him bleeding in the pool, causing everyone to think he has [=AIDs=]. After this happens, Dee, Mac, and several kids fall into the water. Now, we know they don't have [=AIDs=], but what if they now have that terminal illness Frank was diagnosed with? We don't know if it's bloodborne or not.

* It's increasingly demonstrated that Mac is ArmouredClosetGay, so in the season eight episode "Frank's Back in Business," you might wonder why he immediately checks out when he and Dennis mistake a caddie for a male prostitute. However, Mac is always obsessed with huge, muscular bodybuilders. Because the caddie is a young, slender boy, he's not Mac's type.

* In "Sweet Dee Gets Audited" there is a debate between the characters about what to do with the corpse of a dog that is rotting in the alley behind the bar. Mac and Charley want to perform a 'dog funeral', while Frank and Dennis want to throw the corpse in the dumpster. Mac probably supported the dog funeral because other episodes have shown that he still owns an old dog that he is emotionally attached to, so it makes sense that he wants to bury the dog with dignity. In addition; Mac is a hardcore Catholic, so it makes sense that he would place so much value on a proper burial. Alternatively; Frank has expressed the opinion that a dead body is essentially trash, to the extent that he does not care what happens to his own corpse when he dies. Dennis, in addition to being a sociopath, has expressed the opinion that eating a dog is no more morally wrong than eating a chicken.

* Charlie's "Nightman" song. Since the show did drop hints on the possibility that Charlie got molested as a child the song could actually be about Charlie being sexually abused as a kid.

* In "Frank Is Back in Business", Dennis spends the episode "getting off" by pretending to be a man named Brian [=LeFeve=]. Later, Mac explains that the real Brian [=LeFeve=] was stabbed to death outside of Paddy's by a crackhead. Who's a crackhead that hangs around Paddy's Pub? [[SerialKiller Dennis.]]
** He even "gets off" at seeing Brian's severed finger in a plastic bag.
** Later, upon being compared to a serial killer, Dennis remarks that ''[[ITakeOffenseToThatLastOne serial]]'' killer is an exaggeration.

* In "High School Reunion," an astute viewer might realize a few seconds early that the dance scene is a fantasy sequence because their choreography incorporates Dee's back brace - which she was ''clearly'' not planning to wear that night.

** His uncle Jack carries around a picture of [[{{Shotacon}} "art"]] around with him in "Gun Fever: Still Hot". Is that picture of Charlie, or another kid?

** Given that all of the victims were young blonde women, it's very possible that the Waitress could've been next...

* The idea of "The Nightman" also involves "The Dayman" (Charlie). The actor who plays Charlie has the surname "Day," which may have had a part in naming the "Dayman" character.

!!FridgeLogic:
* In "Chardee [=MacDennis=]: The Game of Games", the Gang states that one of the rules is that once the game starts, no questions are allowed. As early as their first turn in Round 1, Mac asks Charlie two questions ("Ready, Charlie?" and "Who else would have written this?").
** The gang is not exactly known for its integrity and memory.
