The Blonde and the Pop Machine

A blonde woman was standing at the pop machine; she put in her money and pressed the Coke button and out came a can of Coke. She looked at it and smiled. She took out a dollar, put it in the pop machine pressed the 7Up button and out came a can of 7Up. She looked at it and really started smiling. She put in the change from her dollar and pressed the Coke button again, out came another can of Coke. Then she was just beaming!

There was a man standing there watching her, and he finally went up to her and said, "What are you doing?" She looked at him and said, "Duh, I'm winning!"
