I was playing with the kids last night, and tried something I had never shown them before - that trick where you pretend to separate your thumb into two pieces. It totally freaked their beans. They couldn't figure out how I was doing it, and Sean kept trying to pull his own thumb off until I told him that only grown-ups could do it. He then proceeded to try and pull MY thumb off. It was a ton of fun. Now I've got to try and remember all of the other kid-fooling tricks I used to know.
