A blonde wants to earn some money in her neighborhood to pay some bills. She starts ringing doorbells and at one house she offers to to do whatever painting job is wanted.

The guy who answers the door tells her that he would like to get his porch painted.

The blonde offers to do it for $50. The guy says: " It's a deal" and they agree on yellow for a color.
Later in the morning, the guy is speaking with his wife and tells her about this deal he made. The wife, being a nice woman, tells her husband:" Didn't you tell her that the porch goes all the way around the house?". The guy tells her that the blonde had accepted the deal so "Leave it alone!"

The blonde shows up at the front door a few hours later to be paid.

The blonde says: " I did the job and I also gave it two coats of paint".

The blonde adds: " By the way, it's a Ferrari and not a Porsche".
