Porsche
There was this blonde applying for a job and saw a sign that said "Help needed for paint job. Come here."
So she went to the house and knocked on the door. She said, "I'm here for the paint job."
The man who answered said, "Okay, here's the paint. I want you to paint the porch."
She said, "No Problem," and set off to work.
She finished the first coat and decided because it didn't take very long she would give it a second coat. She finished the second and knocked on the door.
She said, "I gave it two coats and oh, by the way," she continued, feeling very intelligent, "it's not a Porsche, It's a Ferrarie."
