"500 Dollars" joke
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 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 jerk had $500 in quarters!"
