The Painter & the Porch

The painter arrived in the morning, and the homeowner spelled out exactly what he wanted done: "I want you to paint the porch out front. I've already purchased the paint - it's the best. Once it's on - it'll never come off. I expect this to take you all day, but I am willing to pay very well."

About halfway through the day the painter came back - he was done. "Wow, you're done? Great. Here's the money and a big tip for doing the job so fast."

The painter replied, "Wow cash. Thanks! And by the way --that's not a Porsche. It's a Mercedes."
