My thoughts on seeing Larry in the battle suit: "He's what - the third person to put it on, besides Kim? That suit's got to be stretched w-a-y out of shape by now. How could any of those guys (Ron, Dementor, Larry) possibly fit into a suit designed and tailored for someone who's taller and slimmer then they are?"
I also hope Larry washes the suit before giving it back to Kim... :P
