Because no guy on Earth has ever ceased to think the Stooges are funny.. that farting isn't funny, even burps - hilarious.. It doesn't matter how old you are, or how mature, or how settled down you are.. Stooges, farts, and burps are funny from the first time you hear them - and expel them - right up until your very last one..
You simply NEVER outgrow the humor of those 3 items..
Friendship is like peeing your pants.. Everybody can see it, but only you can feel the warmth..
