This is why they should show more older stuff, almost everything on TV is fart humour or characters saying really random things, Kids should see different styles of humour, it balances them out.
I honestly don't know if I found farts and other toiler humorisms funny. I do know that I avoided Ren & Stimpy like the plague. I thought it was really gross
Toilet humor can be funny when executed correctly. Cases in point: The end of "Drip Along Daffy" ("Lucky for him, it -is- a one horse town!") and the dead body chalk outline in "Robots". Also an honorable mention to Peter Griffin and Michael Moore's farting contest which gradually becomes a synchronized melody/harmony.
