Sulley Was Murdered and Turned Into a Toilet Seat Cover
This spans beyond the limits of Monsters, Inc. and includes a Toy Story special short titled “Partysaurus Rex.” There’s a scene in Monsters, Inc. where Randall tells Sulley that he “…heard humans skin monsters and make toilet covers out of their fur.” Then, in “Partysaurus Rex,” there’s a toilet seat that most definitely looks like it’s made of Sulley’s fur. This is sad, but so detailed that one has to respect the subtle, albeit dark little nugget of humor.
Middle Fingers Up
Mike is trying to send Boo back through a random door, but Sulley argues with him, resulting in things getting heated. Mike yells, “Now put that thing back where it came from, or so help me..!” His middle fingers are raised, but he stops his hollering once he realizes everyone is watching him have his freak-out.
Mike Thinks Sulley Is a Peeping Tom
When Sulley is searching for Boo in the men’s restroom, he crawls on the floor to peek under the stall doors. When Mike walks in, he gives a confused, “What are you doing?” presumably thinking Sulley was watching people use the restroom like a creeper.
Waternoose Drinks Poop
Waternoose is shown filling his coffee cup with something that sputters out with the sound (and appearance of) feces. Potty humor + adult humor = this.
Celia Thinks Mike and Sulley Are Lovers
There’s a scene where Mike and Celia have a dinner date, and they have an exchange that goes as follows:
Mike: Someone asked me who the most beautiful monster in Monstropolis was, and do you know what I said?
Celia: What’d you tell them?
Mike: I said… [MIKE SEES SULLEY AT THE WINDOW] Sulley?
This confuses Celia, who is now under the impression that Mike and Sulley are romantically interested in each other. Late, Mike and Sulley are having a chat and they’re hidden behind the restaurant menu, which annoys Celia, who is further convinced that the two have a more-than-friendly relationship.
Exposed Monster Private Parts
When George has a sock on his back, the CDA hastily removes it, but the contamination detox isn’t over just yet. They raise up a curtain as they shave George’s entire body then spray him with water. When the curtain is lowered he’s standing there covering his crotch, until a CDA agent tears a bandage from his back, resulting in him screaming and exposing himself.
Pee Snow Cone
After being trapped in a blizzard, Sulley and Mike are saved by a Yeti who offers them shelter and snow cones. These snow cones are yellow, drawing a grossed-out look from Mike, who thinks the yellow is from urine. The Yeti lets him know that it’s lemon flavoring – not human waste.
