Have you seen my keys?

James has a new key fettish. Each morning, he looks for my purse and steals my keys so that he can go around the apartment and unlock all the cupboards and doors. Anything that looks like a keyhole, he is sure to put the key into. Luckily he's only tried to put the key into a socket once and we caught him before he could actually succeed. I think we scared him so much that he doesn't even want to try it again. I think the funniest place he's tried to "unlock" is his bellybutton.
