A man is walking down the street

As he's walking down the street he comes up to a prostitute that says "I'll do anything for $300", the man asks "anything?" The prostitute replies with "yes". So the man goes away to the money machine and gets $300, after getting the money he asked once more if the prostitute means absolutely anything, yes, but only if you can tell me in 3 words she replies. He's goes away and thinks for a little bit, after returning he takes the money out and hands it to her and says "Paint my house"
