Soda Machine

A blonde walks into a bar and stands in front of a soda machine. She puts 50 cents in and a soda comes out. She puts that one down, puts in another 50 cents and another soda comes out. The blonde continues to do the same thing over and over for an hour and the bartender starts wondering what she's doing. Finally, he goes up to her and asks what the hell she's doing. She giggles and replies, "I'm winning!"
