A Puzzler

Today, when I picked Lulu up at school, I peeked in the door and her teacher was quizzing her on her colors, which she got all right, and when she was finished I said, "Who's the smartest baby ever?" and she said, "My mommy!!" and ran over to me. After we got done giggling about the fact that her mommy is not the smartest baby ever, her teachers told me that she didn't eat any of her lunch. Not one bite. They said it was because she pooped outside and got REALLY MAD. ??! They'd never seen her so mad, and all because she pooped. Outside. Huh? She was wearing a diaper.
