A homeless man knocks on a woman’s door.
“Spare a few bucks? Maybe some food?”
The woman thinks for a moment.
“You could do some work instead. Paint my porch and I’ll give you $30. There’s green paint and a brush over there.”
An hour later, she checks—no man, no paint. Suddenly, there’s a knock at the door again.
It’s the same man, covered in green paint, beard included, grinning from ear to ear.
“All done, ma’am! By the way… it’s a Cadillac, not a Porsche.”
