Replying to Funniest thing that has happend in a class

in grade eight I was in math and there was this class clown kid,  the teacher was a total bitch so we would always fuck with her.  One day the teacher left the class for about 10 minutes and this class clown kid hid behind a bookshelf, the teacher came back and questioned where he was and everyone was giggling.  Then out of no where I hear possibly the wettest fart that I have ever heard and this clown comes out from behind the bookshelf nearly crying because he was laughing so hard.  Not so funny anymore now that I think about it, but in my immature eighth grade mind that was the funniest shit ever.  Anyways post some funny stories!
