Two men walk into a bar, one wearing a cowboy hat and the other wearing a Yankees cap. The guy in the Yankees cap approaches the bartender and make a bet: "I'll bet you $1,000 that I can put a shot glass at one end of your bar and piss into it from the other end of the bar without spilling a drop."
The bartender laughs and says, "You're crazy, but you're on."
The man positions a shot glass on one end, walks to the other end and unzips his fly. He then pisses everywhere -- all over the walls, over the bar top, all over the bottles of booze, and all over the bartender. The bartender roars with laughter and tells the man to pay up.
The guy in the Yankees cap pays up, laughing and smiling, too.
"What are you smiling at?" asks the bartender. "You just lost $1,000!"
