Blonde Painting a Porch

A blonde walks up to a man standing in his back garden and asks for food. He replies, "I have worked hard all my life to earn money to buy food and do not believe in giving people something for nothing. Paint my porch green and I will give you food." The blonde agrees and goes round the front. She returns two hours later. "I painted it," she says to the man, "but there is something you should know. Its a Ferrari, not a Porsche."
