Johny so badly wanted to have sex with a girl on his job, but she had a boyfriend so he couldn't. Yet one day he asks her:
"I want to have sex with you. I will pay you $500 for it."
"No way Johny!" she replies.
"Listen, I will throw the $500 on the floor, you will bend over and I will have sex with you until you have picked them up. No longer, no less."
She calls her boyfriend and tells him the story. The boyfriend says:
"Make him pay $1000, then you pick up the money as fast as you can. So fast that he even won't get out of his pants."

Johny agrees to the rules and throws the money on the floor.
The boyfriend waits 45minutes before his girlfriend returns the call.
He asks her:
"How come it took so long?"
"The bastard payed me with coins!!"
