Scene: In the kitchen, at his breakfast table.
Me: Oooooh, C! I have a funny joke for you!
The Boy: What is it?
Me: Why didn’t anyone like to play with the crab?
The Boy: Why?
Me: Because he was shellfish!
The Boy: (deadpanned) That’s not a funny joke, Mommy.
Me: (laughing) Okay.
The Boy: It’s really not. I’m serious.
Me: (serious) Sorry.
The Boy: I’ll tell you a really funny joke.
Me: Okay. Go for it.
The Boy: Knock, knock.
Me: Who’s there?
The Boy: Banana.
Me: Banana who?
The Boy: Banana bun.
