Poo Poo on the Floor?

Brody came up to me today, very excitedly. In his hand he held a napkin with a flake from his Special K cereal that he ate last night. He tapped my leg and said "Wook Mommy! Wook! I throw in trash!" I said "Okay! Good boy! What is it?", to which Brody responded with a disgusted look on his face "Poo Poo."
