I forgot to mention this new game that Nick made up. Aunt Becky was taking care of Elizabeth in a studio at Sears that was not being used when Nick came to see what was going on. He was away from the door, thankfully, when he asked Aunt Becky if she wanted to play the "Buddy Game."
Aunt Becky: What's the Buddy Game?
Nick: The Butt Game!
He preceeded to turn around, pull down his pants AND his underwear, and wiggle his butt at Aunt Becky. If you are the one who taught Nick how to do this, you now have a time out!
