Jon is reading jokes aloud for Caleb. He comes to a knock-knock joke.
Jon: Knock knock.
Caleb: Wait! I know how to do this. I'll teach you the rules.
Caleb: First, I say, "Knock knock." Then you say, "Who's there?" Then I say a silly word, like "Blah be boo." Then you say, "Blah be boo, who?" and I say another silly word!
Okay, so Knock Knock!
Jon: Who's there?
Caleb: Nutty vue.
Jon: Nutty vue, who?
I gotta admit, I laughed. I wasn't expecting "Tot!" Haha! That's a pretty funny joke, right there.
