hehe The "not me" reminded me of this:
One morning I came out of the bathroom after my shower to see the Trivial Pursuit game scattered all over the living room floor ... every card was out of the box and every little slice of every pie.
I didn't say a word to my son, who was about three at the time, but gave him one of those Mom looks. He cocks his head at me and said, "Did you see me do it?".
Pretty hard to be mad when it takes everything you have not to crack up laughing. Was also pretty hard to explain that since there were just two of us there and I knew that I wasn't involved, it pretty much left him.
He still tries that same phrase when he's trying to feign innocence.
