A Conversation with Charlie (Age 5) About Superheroes

HIM: So in Batman is The Joker a funny guy?
ME: Not really, no. He's mean.
HIM: But he makes jokes!
ME: Yeah, but he's not really funny.
HIM: Well, what kind of jokes does he make? What kind of jokes aren't funny?
ME: Maybe ones that make fun of people.
HIM: Or boring ones! Maybe he makes boring jokes! Like, knock knock.
ME: Who's there?
HIM: Oh (long pause) ...work...
ME: That's the joke?
HIM: Yeah. Maybe The Joker makes jokes like that.
ME: So he's got a super power of making really boring jokes that aren't funny?
HIM: Yeah, I think so.
