** HumanoidAbomination: One notable cartoon has a flasher exposing his tentacled, multi-eyed, multi-mouthed torso to a terrified woman.
* DadaComics
* DinnerOrderFlub: One cartoon shows a patron with an inedible pile of ashes on his plate, while a snooty waiter says, "It's a burnt telephone book. We gave it a fancy French name and you ordered it."
* FarSideIsland
* FluffyCloudHeaven: A frequent subject. One notable subversion shows some angels (basically guys in cheap costumes with cardboard wings and wire halos) standing around in a small grubby room labeled "Heaven", with one of them commenting "I expected the place to be a lot more classy!"
* FreudianCouch: This is a particular favorite with him.
* GhostStory: "Campfire Story" centers around one that may or may not be Main/RewritingReality.
* HaveANiceDaySmile: He ''hates'' them, feeling they represent [[StepfordSmiler phony]] or [[HappinessIsMandatory enforced]] good cheer. He's gone so far as to do a cartoon with a Hitler {{Expy}} whose symbol is the smiley face rather than the swastika.
* InfantImmortality: Averted constantly.
* IsNothingSacred: There's a cartoon in which ornately robed monks are praying to an ornate but quite empty pedestal. A passerby utters the phrase in question.
* LivingStatue: "The Marble Boy"
* NightmareFetishist: Gahan himself, but he also did a cartoon of a man painting a picture of horrific nightmare beings, cheerfully telling an anxious onlooker "I paint what I see!" - and this was the title of one of his cartoon collection books.
* RageAgainstTheAuthor: "The Power of The Mandarin"
* RewritingReality: Many of his short stories use this as a plot point.
* SantaClaus: A popular subject, usually messed with in some hilarious way (being a werewolf, being an child-harvesting alien). WordOfGod is that a favorite cartoon was one where a chimney sweep tells a lady "Well, we found what's been clogging your chimney since last December" as they stand over a skeletal body in a Santa Claus outfit...
