"Good day, sir. I was wondering if you had any painting you need done."
The owner of the house, a rich man by any standard, looks speculatively at the painter. He perceives a vibrant entrepreneurial spirit, which reminds him of his own ambition in his younger days.
"Hmmm. Yes, I think my porch needs a coat or two of paint."
The eager young painter rushes off around the side of the house...
Several hours later, he returns to the front door, his clothes dripping paint, and knocks again.
"Sir, I've finished! But I have to tell you, that wasn't a porch, it was a Ferarri."
