Here's one that I still laugh at:
its called "Fart Football"
A guy decides to go a gay bar curious as to what goes on and how it differs from his local bar. So, he goes in and gets boozed up, then decides to make small talk with the regulars. Intrigued they offered him to play fart football. Trying to fit in he asks "How do you play?" They reply, "Its simple, all you gotta do is pull down your pants like this, and crack the loudest fart you can, and then Call 'Touchdown'! (pulls up his pants) Then the guy with the loudest fart wins". Simple enough, decides the man, so he drinks some more and says "Ok I got a good one ready". So the man pulls down his pants, bends over and just as he is about to fart one of the guys jumps infront and yells "BLOCKED!"
