Knock Knock Jokes

My wonderful little boy Jacob (20 months old) has begun telling knock knock jokes, it is hilarious. He just comes up and says "Knock, Knock", I say "who's there", he says "jabber, jabber, jabber" then he says "knock, knock" again. We do this for a few minutes at a time, it just cracks me up. I am hoping to get a video of him doing this soon.
