Johnny wanted to screw a girl in his office but she belonged to someone else. One day Johnny got so frustrated that he went up to her and said I'll give you a $100 if you let me screw you, but the girl said NO.
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, so she called her boyfriend and told him the story. Her boyfriend told her "ask him for $200, pick up the money very fast, he won't have time to remove his trousers or even unzip his fly. So she agreed and accepted the proposal.
Half an hour went by and the boyfriend was still waiting for his girlfriend to ring. Finally after 45 minutes the boyfriend rang her and asked what happened. She replied "The bastard used pennies"
Management lesson: Always consider a business proposal in it's entirety and verify all the details before agreeing to it and getting screwed!
