Dorothy: Let me try this out on you.
Sophia: OK, make me laugh.
Dorothy: All right. Here we go. It seems there was this doctor-
Sophia: "It seems" there was? What is this, existentialist humor? Was there a doctor, or wasn't there?
Dorothy: Yes. Yes, there was this doctor. He's sitting in the park.
Sophia: What time of year is it?
Dorothy: What difference does it make?
Sophia: You have to set the scene.
Dorothy: Who is telling this joke?
Sophia: At the moment, nobody.
