What really matters...

I am learing some pretty important things in NYC about comedy... I am not talking about the stuff everyone knows, like giving people time to finish applauding... I am talking about the little hidden things like what people really think is funny... for example, fart jokes ... always funny... but explosive diarrhea not always funny, yeah yeah sure people laugh, but eventually they realize you just shit your pants and then they stop laughing... then it sorta turns into "hey this guy isn't so funny?"
