The poor guy walks up to the rich guy's house.
He's down on his luck and needs some money. He rings the doorbell.
"Hi there, I'm down on my luck, need some money, and I was wondering if you have any work I could do for you?"
The rich Guy decides to give him a break, and says: "Sure, my porch needs painting. I'll pay you 50 quid to do it for me." "Sure thing, Mister, I'll get started right away!" Time passes, until... "Hey Mister, I'm all done painting!" "Well, here's your 50 quid" "Thanks, and by the way, it's a Ferrari, not a Porsche."
