Johnny wanted to have sex with a girl in his office but she had a boyfriend.
One day, Johnny got so frustrated that he went up to her and said, "I'll give you $500 dollars if you let me make love to you." The girl replied, "No way!" Johnny said, "I'll be fast. I'll throw the money on the floor, you bend down, and I'll be finished by the time you pick it up."
She thought for a moment and said that she would have to consult her boyfriend. She called her boyfriend and told him the story. Her boyfriend said, "Ask him for $1000 dollars, pick up the money really fast, and he won't even be able to get his pants down." So, she agreed and accepted the proposal.
Half an hour goes by and the boyfriend waited for his girlfriend to call. Finally, after 45 minutes, the boyfriend called and asked what happened.
She said, "The bastard used quarters!!"
