Pee in the bar

A guy walks into a bar and orders a drink. Then says to the bar tender, "I'll bet you one-hundred bucks that I can pee in this cup from straight across the room." The bar tender says, "You're on." The guy then buys two more drinks, and puts his money on the table. The guy then goes across the room and pees all over the place not once getting it in the cup. The bar tender takes the money and smiles. The guy smiles back at him. The bar tender asks, "Why are you smiling? You just lost one-hundred bucks." The guy then says, "I bet everyone else in the bar one-thousand dollars that I could pee all over the place and make you smile!"
