- Mr Potter, you just come over here with me.
- Now, does that sound like Doris?
- Well, I don't know. I've never hit her with a pipe.
- Look! She's solid like a rock. Go on, feel it for yourself. Go on, feel it.
- Wouldn't you be, standing around with nothing but your corsets on?
- Wait a minute, I've just remembered. I might be able to prove it's Doris.
- Well, Doris had a little birthmark on her...
- On her what? Are you sure? How do YOU know?
- All right, Mr Potter. If it's going to make you happier, go ahead and have a look.
- What? In front of all these people? What do you think I am?
- Well, some fool's got to do it. It isn't going to be me!
