Magic

I confess that I only know two real magic tricks. I can turn a cat into a squirrel - and then back into a cat.  Unfortunately, it is part of the spell that, throughout the event, the cat/squirrel must remain in a box and no peeking is allowed.  Oh, and I can take the top of my thumb off, and put it back - without a box. But I guess everyone can do that one, so it probably doesn't count.
