A cab driver pulled up at a stop sign near Central Park in New York. A stark naked woman jumped out from behind a bush, opened the back door of the cab and demanded to be taken to the airport. The cab driver kept looking back at his passenger in the rear view mirror, and she became irritated and said, "Why do you keep staring at me?" The cab driver replied, "Well, you don't have any clothes on and no place to carry any money and I am wondering how you are going to pay your fare?"

The cab driver looked back at the woman and said, "Do you have anything smaller?"
