knock knock

We know what Brody is trying to say with his first knock knock joke, but it isn't coming out quite right. "Knock Knock", who's there? "Banana", banana who? "Banana Orange". When we try to explain that he's supposed to go through many iterations of banana before saying "orange you glad I didn't say banana?" he tells us we're wrong.

Logan listens to Brody closely enough that this morning he called to me over the kitchen table saying "knock, knock, knock, knock..." When I finally realized what he was saying and asked who's there, he said "Orange", orange who? "Orange Banana".
