A boss said to his secretary, "I want to have s*x with you.... I will make it very fast. I'll throw $1000 on the floor, 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, pick up the money very fast so he wouldn't even have enough time to undress himself." So she agrees. 

Half an hour goes by, the boyfriend calls his girl and asks, "what happened?" 

She responds, "He used coins and I'm still picking!"
