So this Mexican is walking down the street, looking for work. He comes up to a house with a sign "Painter Needed". He goes up to the house, rings the bell, and talks to the owner.
Owner says, "I need my porch painted. It's out back. Paint, brushes, water to clean up with, and when you're done, come back up front and I'll give you fifty bucks."

Mexican says, "Good deal," and goes to work.

A couple hours later, he comes to the front door, tells the man the job is done and collects his money.

As he is walking away, he turns and says, "By the way man, I should tell you.
That's no Porch, that's a Mercedes."
