Blonde handyman

A teenage blonde in need of some money decided to hire herself out as a handyman and started canvassing the neighborhood.
She went to the front door of the first house and asked the owner if he had any odd jobs for her to do.
"well you can paint my porch," he said. "Howmuch would you charge?"
"How about $50 ?" she answered.
The man agreed and told her the paint she would need was in the garage.
The mans wife overheard the conversation and said to her husband, "Does she realize the porch goes all the way around the house?"
"She should," the man answered, "she was standing on the porch while we talked."
A short time later the blonde came to the door to collect her money.
"You'r finished already ?" he asked. "Yes," The blonde answered. "and I had paint left-over so I gave it two coats."
Impressed the man reached into his pocket for $50. "And by the way," the blonde added, "that's not a Porch, its a Ferrari."
