This thread reminded me of a joke.
Bobby wanted to have sex with a girl in his office, but she belonged to someone else.
One day, Bobby got so frustrated that he went up to her and said, "I'll give you $100 if you let me screw you. But the girl said no.
Bobby 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. So she called her boyfriend and told him the story. Her boyfriend says, "Ask him for $200, pick up the money very fast, he won't even be able to get his pants down."
So she agrees and accept the proposal. Half and hour goes by, and the boyfriend is waiting for his girlfriend to call.
Finally, after 45 minutes, the boyfriend calls and ask her what happened?
"The bastard used coins!" she responded.
