My body hurts!

Sometimes Barrett skins his knees or cuts his finger or bumps his head.  It doesn't matter what he hurts, he typically walks up to me (crying) and says, "My body hurts!"  I'll say, "What hurts?"  and he'll reply, "My BODY!"  After a few back and forths like this I'll ask, "Which part of your body hurts?" and he'll say, "My knee (or whatever is hurting him)."  It cracks me up!
