First Joke

We haven't had a "first" around here for a while, but tonight Emerson just told his first joke.

E: "Why'd the chicken cross the road?"
Me: (a little giggle and an oh geez thought) "Why?"
E: "You're supposed to say, I don't know"
Me: "I don't know"
E: "Because he had to poop."

I didn't say it was a funny joke, just that it was his first. I have a feeling there will be many more bad jokes to come from this little man. And you will find me laughing...
