Yeah, you pretty much brought up that 1 episode of Adventure Time like it was the only one with dirty jokes in it. There's like a laundry list of jokes throughout the series. Especially if TreeTrunks or LSP are involved
another one was when Gumball "helped" Alan (balloon character) in the school restroom. 🤣🤣 Gumball and Regular Show def were adult swim material when released in early 2010's
