Two construction workers work on the 30th floor. One of them has to piss, so the other guy agrees to hold on to him while he leans out a window. Just then the dinner bell sounds and the guy who was holding the other guy runs down to get his food.
On the 20th floor he is stopped by his boss, who asks if the guy he works with is gay. "Why do you ask?" he says.
"Because a minute ago he came flying past my window with his d**k in his hand yelling, 'Where the f**k did that a**hole go?'"
