Have you all seen this video? Remember it from your childhood perhaps? It's Cookie Monster trying to come up with words that start with the letter C, but all he can think of is Cookie. And that's good enough for him.
Miles loves this song, and sings it constantly. Only now, he's made up his own version. It's called "P is for Poopy". And he thinks it's hilarious. Sigh. The joys of little boys. . . :)
