Little Jerk

I was sitting in my chair looking over homework this afternoon and I looked over to notice my soon to be 13 year old looking very skinny.  He's never been a big kid, ever, but he was looking especially small.  So I sent him upstairs to weigh himself.  He weighs 129 with clothes on and he's 5 ft 8in tall.  I want that kids metabolism.

I swear the picture doesn't even do him justice for how small he is looking... and he eats...A LOT!!  I maintain that for this reason he's a little jerk. ;)
