1/0 subverts this as seen in the main page image. Tailsteak decided to be Literal-Minded while creating it, and it turned out as a literal "running gag". (Characters complain within the strip about how bad this joke is.)
Double Subverted in that the Running Gag appears so often, it actuallydoes turn into a running gag. In its last strip after Andy dies Tailsteak says "Wasn't really a running gag, was it?" to which a character responds "Debatable." link
The fine folks of Onrac must have eventually given up on their poor community after it kept getting destroyed.
Summoning circles which are actually squares, hypercubes which are actually spheres, and a snow cone which is 'no cone'. (It's actually a seven-sided cube, the 'stube'. The seventh side is the inside.)
In The Adventuresof Dr Mc Ninja, Dr. McNinja likes to punch things in the face. For example: snakes, Velociraptors, zombies, Dracula... It was even used in a banner once.
Did the good doctor die or have something equally horrible happen to him? Congratulations! It's an anniversary strip!
In Akuma TH, The Undertaker (No, not that one) can read minds... And it's never useful, ever. To the point where "What's the point of being able to read minds if I can't see this coming?" practically became his Catchphrase.
In the last strip of every season of Ansem Retort, no matter what, Zexion will order Chinese food.
Bar'd: Every morning of Vas's work week, Shelia (or whoever else is available at the moment) kicks Vas in the nads to wake him up. It's been played with multiple times.
One of the main Bittersweet Candy Bowl cast is repeatedly lead into saying "Hi, I'm Daisy," much to the amusement of her Double Dash-playing friends.
Bob and George has tons of them, from the line "What? I'm evil, I lied." to Acapulco to Level 10 alerts to the F-word being used on December 1st. It even has a Running Gag of characters complaining about Running Gags..
Brawl in the Family has a number of these. It's quite amazing how many gags it gets out of the premise that Kirby transforms into whatever he eats.
In the later run of Casey and Andy, "Bob was there, too" was added randomly to stories or recollections. Said stories were usually complete by themselves, but Bob shows up to provide an extra character. Casey and Andy killing each other. Repeatedly.
Chainmail Bikini is an example that would have had a running gag if its creators hadn't given up on the comic. Said running gag, they explained later, would have been The Roleplayer's characters being repeatedly killed off. They were two characters in when the comic ended, and mentioned that the readers saw the "gag" as more mean spirited than funny.
The Noodle Incident of Tedd turning Sarah into a Cat Girl. It's actually Played for Drama later on, though, with Sarah admitting that the experience left her with some significant trauma.
In the Warhammer 40,000 fanart by webartist emwhatnott, every single piece contains an Alpha Legionnaire (a Traitor Space Marine Legion whose hat is sneakiness and spycraft) either in Paper-Thin Disguise or not even bothering with it, even in places where there really shouldn't be one like a Necron ship, the Chaos Gods' domain or Holy Terra. They're just that good at sneakiness and spycraft.
Erika and the Princes in Distress: Lagertha keeps getting pooped on by the messenger bird of the royal castle, with the fit of rage that ensues usually resulting in her throne getting destroyed. Even on the postcard portrait of her that was available for a limited time, the bird is present and in the process of pooping. Amusingly, this ended up saving her life at one point, as the bird peed in her drink instead of dropping poison in it.
In Everyday Heroes, the neighborhood moms are named Jane, Joan, June, Jan, Jin, Jenny, and Ginny. The single dads are John and Jean (pronounced "zhawn"... he is from France).
In one Fanboys strip, a guy who's been shot asks Sylvia for help and she assumes it's an April Fools prank that Lemmy set up. After she pranks Lemmy, the last panel is the guy's funeral. The casket and the funeral director in that panel would then be copied and pasted directly into later strips.
Good Tickle Brain: The sub-series "A Stick-Figure Hamlet" has several of its own running gags, including Horatio complaining that his studies didn't include how to deal with ghosts, and every mention of the arras being followed by "—or large hanging tapestry—" "I know what an arras is!"
In Greg, Greg and Ted repeatedly gets petrified by a nude Medusa as they repeatedly fall for her charms.
Guilded Age makes a lot of "But can X see why kids love Cinnamon Toast Crunch?" jokes in the Alt Text.
Or, after some fans misidentified Eglamore, the first strip of every scene with Eglamore in it will point out that it is, in fact, Eglamore — except for one scene that identifies the protagonist instead (as the character standing next to Eglamore). Occasionally the author will instead point out that the (generally non-human) character appearing is not, in fact, Eglamore.
"Jones is not a robot." Tom took great delight in skewering, roasting, and in general stomping on that particular theory any chance he got. This particular running gag seems to have died ever since The Reveal about Jones.
In Hanna Is Not a Boy's Name, the nameless character (usually referred to as Zombie or {...}) is constantly being renamed by his parter Hanna. Some of these names are pretty ordinary, but Hanna comes up with some peculiar ones too, like Gallahad, Imhotep, Socrates and, perhaps the best yet, Ringo.
Irregular Webcomic! has a long-standing joke about characters being killed by "insanely overpowered fireballs" — and a character called Death of Insanely Overpowered Fireballs (who has been promoted and demoted on several occasions).
There are also the deaths by giant frogs. Variants include being sat on, choking on and getting stared at angrily by one.
Then there are the "Hobbit" puns, which are so groan worthy the author has a self-imposed limit of one every 100+ strips.
Nazi science sneers at running gags!
Steve wrestling something to death, even once happened to the Death Of Being Wrestled To Death By Steve.
In Knights of Buena Vista, Mary keeps complaining that their roleplaying game doesn't have Ninja in that setting.
Looking for Group: Anytime people are introduced, or reunited, Richard will pop up with "I'm Richard." Also "For Pony!"
Cale sometimes cannot stop himself from making a "Dick" joke about Richard.
Richard's ever-increasing number of titles:Chief Warlock of the Brothers of Darkness, Lord of the Thirteen Hells, Master of the Bones, Emperor of the Black, Lord of the Undead...Lord of the Dance... The Mistress of Magma...and the mayor of a little village up the coast.
It's very scenic during the springtime.
For a long time, Richard's pet rabbit. In the midst of a dramatic fight scene...the bunny is tagging along behind the panther. And it is not a Killer Rabbit.
"you think you know me"
Tim the Troll's pet name for Cale, screamed every time he reunites with him. "CHICKEN!"
Shaenon freaking out whenever the black oil makes an appearance.
Mulder expressing his theories in the most ludicrous and unsupported-by-evidence manner possible, followed by a panel with a caption saying "BUT OF COURSE, MULDER IS RIGHT!"
In MSF High, Rainer's penchant for Exposition has slowly moved into running gag, complete with a warning sign!
MS Paint Adventures rides this trope like a mechanical bull. They have so many that it's easier just to link their own page in the wiki. No pumpkin here, go away.
Other NC running gags include the spontaneous explosion of Earth, lampshading of Luigi being even more neglected than the rest of the cast, & close-ups of Dr. Donez whenever he's addressed by name, among others.
Neglected Mario Characters used to do a literal running-gag similar to (but earlier than) 1/0, but with an actual character, Churro, running, not the word "Gag."
Niels has Niels and Agent 300 taking each others clothes during kidnappings.
Agent 300 doesn't realize that he and Niels are flirting with each other for real.
The other characters getting annoyed by the flirting and 300's oblivious-ness to it.
Agent 300 bringing up what 250's daughter did to him.
250's conversations with God.
Duncan is an angry black man
Who nobody considers part of the threesome.
In The Order of the Stick, I prepared explosive runes this morning. Likewise, V's familiar that is forgotten by everybody except when they need him to be around. And V's Ambiguous Gender.
Early on, there was the Running Gag of Roy's dad's ghost coming by to give him advice at night. This led to another running gag: whenever he repeated the advice, someone would ask "Isn't your dad dead?" and Roy would nonchalantly respond "Yes." and go on without further explanation.
Also, Elan's illusions almost always end up being a female version of whoever he tries to distract. I count two targets happily married/committed, one gay, and one with a schoolboyish fear of girls (though that one worked to scare him off).
Then there's Elan's recurring hand puppet/personal deity, Banjo.
V's newfound epic power turning out to be unnecessary is a running gag that's been developed in record time.
Falling characters landing on flumphs. Even when Belcar made a flumph from sand. Even a ghost flumph gets flattened by a spirit. The one time it was averted, it was lampshaded in the next comic.
Durkon and his feud with trees. Also lampshaded, as in the page quote.
The Monster In The Darkness not knowing what the gates are. "Gate? What gate?"
"Detect evil/good!" — *lifts lead sheet* — "Stop oppressing my culture, you ethnocentric bitch!"
Nobody is yet sure whether the Resistance is called exactly that, or the Azure City Underground. Or the Sapphire Liberation Front. Or the Rebel Alliance...
When Bud encounters Roddy, he often says "Roddy! What are you doing here?" And boy, does he spin it and spin it - until it is spun right back at him, at long last.
Running gags involving Autumn and her family include jokes about her family reproducing via cloning and library science.
In the "internEt" mini-arc, Rule #4 (first introduced in this strip) has become a running gag and is regularly used in the comments section.
When she still had long hair, Rain usually had a hairstyle which covered one of her eyes, as such, when a character saw her with a hairstyle that showed both of her eyes, they ask "Did she always have two eyes"?
In Rusty and Co., Mimic's proposed plan: the group "disguise ourselves as common, unassuming pieces of furniture".
Or Rusty's proposed plan, AKA just about the only words he ever says: "Eat [metal item]?"
The squirrel Sid from Sandra and Woo is friends with the raccoon Woo and the fox Shadow which does not stop them from trying to eat him on a constant basis.
Schlock Mercenary: Due to an act of sabotage and realising they couldn't get damages off The Partnership Collective (a hive mind of clone lawyer drones with no conscience), the Sol System courts decided to inflict two billion kilocreds of damage on them, hiring Tagon's Toughs to do it. This equates to about a million of these drones. If a snake with a tie shows up, expect Schlock to kill it.
Schlock eats a lot of interesting things, has only one bodily orifice and has no sense of subtlety.
Other characters have lampshaded the fact that they're not willing to rely on the sense of smell of anything that craps out the same hole.
Subverted in that Schlock's whole body is a scent receptor, not merely his mouth.
Schlock has an addiction to 'Genuine Imitation Ovalkwik'.
Ennesby's punning, although this has faded a little with time. At one point, Ennesby mentions that in Galstandard, the name of the enemy ship translates to "Broken Wind" and doesn't make the obvious fart joke pun to go with it, Tagon realizes that they're in real trouble.
After she was introduced, Kathryn's bus was stolen and then destroyed by the Toughs quite a few times.
Ryk demonstrates two different types of Running Gag here.
Second Empire: No one ever listens to Grexzol... but this becomes downright heartbreaking when this is the last thing that is ever said when Grexzol rejoins his former regiment and goes off into the afterlife.
In Sequential Art (the webcomic, not the medium), if Kat doesn't like you, she lets you know. Repeatedly. Bitch.
Shooter's Epic Awesome Adventure of Manliness has Beat. He appears multiple times throughout the series, always saying 'Im Diggin' it' at least once. Beat has had an issue devoted to him in the first series and After Story, and got an Entire Arc in Yellow After. Due to Kanon's inability to plan ahead, 80% of the time he will be killed off in some manner.
You could say people coming back from the dead is a Running Gag itself. Even though they get killed again.
To a Lesser Extent, Pheonyx and Sho & Shyo. Also, Batlion, Suitlion and OmegaBatlion
Slightly Damned has Buwaro's tendency to play catch with his pet rock Thadius, which usually results in a fairly nasty headache for someone. Also, a certain pimp suit has been causing problems for a while now...
Aversion: The title and author's notes of Found By: Zalgo implied the author was either going to or trying to make a running gag editing a strip where Jon's father finds him and Garfield hiding in the closet so that various fictional characters found him instead. However, nothing else came out of it.
In Star Mares, Fettlock's Memetic Badflank status is constantly lampshaded by one character declaring him to be 'so cool' and another not understanding why.
Tower of God — QuantBlitz's face is on every possible product, making him the Tower's greatest corporate whore... or not. Word of God explains that Yu Hansung got the portrait right to his image and is using it to make money after he was fired (Quant cries every time he sees one of them).
