Office - Show Me the Money
A boss said to his secretary I want to have sex with you and I'll make it very fast. I'll throw $1000 on the floor and by the time you bend down to pick it I'll be done. She thought for a moment then called her boyfriend and told him the story. Her boyfriend then said to her, "Do it but ask him for $2000, if you pick up the money very fast he won't have enough time to undress himself."
So she agrees. Half an hour goes by, the boyfriend decides to call girlfriend, he asks, "What happened?" She responds, "The bastard used coins."
