Bandit: Eh but Dylan, you are a rabbit!
Dylan: What? Oh no, I keep forgetting that.
Bandit: So what are you going to do now?

Bandit: No Dylan, no! They really are dogs.
Dylan: So that's why we never get to meet them! Have you any ideas?
Bandit: Well, nowadays, most rabbits dress up as witches, ghosts or zombies.
Dylan: Zombies? That pop group from the sixties?
