I am not exactly proud of the fact that I used the old chicken butt joke to teach Henry about the concept of jokes. The origin of the joke goes back to when we understood the word butt to mean shoulder, but no matter. Today, we understand butt as the posterior and that is what makes the joke…
I had to explain the joke with narrations:
[Henry, you’ll say] Hey, guess what?
[I’ll say…] What?
[Henry, you’ll say] Chicken butt!
It took Henry two times to say the joke without offering the narrations or the response, but he nailed it on the third try. Then, he went in to play a joke on mommy and he nailed it again.
