First, a bit of background. My daughters love that stupid, "Why did the lady throw the butter/clock out the window" joke.
My son asked, "Why did the man stand under the window when the lady was throwing butter out?" The answer was, "Because he was hungry."
TheBoy also asked, "Why did the man get in his car and drive away from the house where the old lady was throwing butter out the window?" The answer, of course, was, "Because he wanted to get far away from the crazy lady throwing things out the window."
