A woman was walking down the street when she was approached by a man.

The man said, " I must have you right now! I'll drop 500 dollars on the ground at your feet and in the time it takes for you to pick it up I can have my way with you from behind!"

The woman thought it over and told the man to wait a minute. She called her girlfriend on her cell phone and told her about the man's proposition. Her girlfriend said: "When he drops the $500 on the ground, I'm sure you can pick it up and run before he gets his pants down. Call me back and tell me what happened."

An hour and a half later the lady called her girlfriend back. "What happened?" the girlfriend asked.

The lady said " That motherf****r had $500 in quarters!"
