Okay, more from my little brother:

My mom and I have just gotten home from the gym, where we've also taken the two little kids because there's a little play place there where you can leave them while you work out. It's not a bad deal. There's a ball room. I was jealous. Anyway:

Mom: [notices bite marks on Andrew's arm] Oh my gosh! Who bit you?
Andrew: [Imediately] Notme!
Mom: [Without missing a beat] You BIT yourself?!
Andrew: [Guiltily] Yes... :::sigh:::

Maybe I'm the only one who thinks this is funny... but geez, whatever's wrong with him, I hope it's not catching.
