A blonde, wanting to earn some money, decided to hire herself
out as a Handyman and started canvassing a wealthy neighbourhood.
She went to the front door of the first house and asked the owner
if he had any jobs for her to do.
"Well, you can paint my porch. How much will you charge?"
The blonde said, "How about 50 dollars?"
The man agreed and told her the paint and other materials that she
might need were in the garage. The man's wife, inside the house, heard
the conversation and said to her husband, "Does she realize that the
porch goes all the way around the house?" The man replied, "She should;
she was standing on it."
A short time later, the blonde came to the door to collect her money.
"You're finished already?" he asked.
"Yes," the blonde answered, "and I had paint left over, so I gave it
two coats." Impressed, the man reached in his pocket for the $50.
"And by the way," the blonde added, "it's not a Porch, it's a Ferrari."
