Halloween costume idea

So there was this kid in WalMart last night. He was in the cart being pushed around by mommy. I'm assuming he was 3 maybe 4.

He had a corn dog in his hand, but he had pulled his arm all the way back into his sleeve.

So at first glance, it looked for all the world as though he were eating his own arm.

Really made me do a double take when I saw it.
