Favorite Joke

I have lots of "favorite" jokes. I am not exactly sure what "joke" was Dad's favorite, but I remember him telling this one (and I can remember him chuckling vividly as he said the punch line):

A guy meets a hooker in a bar. She says, “This is your lucky night. I’ve got a special game for you. I’ll do absolutely anything you want for $300, as long as you can say it in three words.” The guy replies, “Hey, why not?” He pulls his wallet out of his pocket, and one at a time, lays three one hundred-dollar bills on the bar, and says, slowly: “Paint…my…house.”
