Any joke, no matter how vulgar, offensive, or inane in any context can be funny if cleverly done. Or done in a way that's so incredibly stupid, it's clever. I.e. the Ren and Stimpy episode where Stimpy farted and spent the entire episode looking for it, like it was his son... or my favorite Japanese superhero, Kinnikuman who flies by farting. Not so much bad, poorly placed fart jokes in kid's movies. You have to actually do something with it for me tio think it's funny. It has to have a purpose.That's an interesting development...
