Knock, knock

Our two year old has starting telling knock knock jokes. He learned them from Jeff, and it is the funniest thing to watch Jack tell his "jokes." This is how it goes:

Jack: Gock, gock (pushing his fist out in front of him as if he is banging on a door).
Me: Who's there?
Jack: Appow (apple).
Me: Apple who?
(a pause)
Jack: Gock, gock.
Me: Who's there?
Jack: Appow.
Me: Apple who?
(another pause)
Jack: Gock, gock.
Me: Who's there?
Jack: 'Ana (banana).
Me: Banana who?

And so on and so forth.. He learned the joke from Jeff, but actually it is Jack's version of the old "orange and banana" knock knock joke. The other day, I asked Jack if he wanted orange juice with his breakfast, and he paused for a moment and then said, "Gock, gock!" ready to launch into the joke at the sound of the word "orange." The boy never fails to amuse us.
