The Food Chain

Jack: What do we need to buy at the grocery store?
Me: We need snacks for your baseball game, milk and salmon.
Jack: Do you know where they get salmon?
Me: ummm, yeah.
Jack: A fisherman catches the fish, kills it, puts it in a box, you buy it at the store and cook it. That salmon was a little fishy once.
Me: Yes it was. Do you know where hamburgers come from?
Jack: No.
Me: From cows.
Jack: I know milk comes out when you squeeze a cow's privates, but I didn't know they poop hamburgers!
