Poop in the potty!

I asked Calvin if he went poop at school today and he said "yes." I asked him who changed his diaper and he said "miss rose.". Then he said "me go 'nother poop. Me go poop in pobby.". So I said, "ok" and let him sit on the toilet as I have several times before (to no avail). A minute or less later he stood up and there it was! Poop in the potty! Go Calvin!
