A beautiful woman was walking down the street when a man approached her. 

The man said, "You are perfection, I must have you right now! I'll drop £500 at your feet and during the time it takes for you to pick it up, I can have had my way with you roughly from behind!" 

The woman thinks it over and asks to the man to wait a minute. She calls her friend and asks her opinion. 

Her friend says, "The man's an idiot, take it because when he drops the £500 on the ground, I'm sure you can pick it up and run off before he can even get his tackle out." 

Two hours later the lady still hadn't phoned her friend back, so the friend phones her instead. 

"Well, What happened?" she asks. 

"The fucker had it in 50p's!!"
