A guy walks in a gay bar even though he is not gay. He is just thirsty.
He goes up to the bar and says I want a water please. The bartender asked, "are you gay?" The guy said no. The bartender said, "If you ain't gay you cant get nothing to drink here."
The guy said, "Come on man! I am so thisty I could lick the sweat off a cows balls!" Then a guy in the corner said, "Moo moo big boy."
