As the absent-minded professor prepared to leave for work, his wife told him, "Don't forget: we're moving today. If you come to this house this afternoon, it'll be empty."
But predictably, he didn't remember until he was standing before the empty house. He mumbled, "Where were we moving?"
A little girl skated past. He asked, "Excuse me, little girl. Did you see a moving van here today?"
"Yes," she replied.
"Can you tell me where it went?"
She said, "Sure, Daddy. I'll show you!"
