Boyce: Can I have it back, please? My potty putty?
Dr. Alan Statham: Well, I daresay you can. You're a big, strong boy and I've no doubt that if I were to give it back to you, I'm sure you could hold it and therefore have it in your possession.
Boyce: May I have my potty putty back, please?
Dr. Alan Statham: Thank you.
Dr. Alan Statham: There you go, take your p-p-potty putty and go and do some growing up somewhere else!
Boyce: Oh, er, by the way, Professor McMay does want to come to your lecture... Professor McMay from pedantics.
Dr. Alan Statham: I don't know any Professor McMay.
Boyce: Oh, sorry, did I get it wrong again? Sorry. Professor McCan from paediatrics.
Dr. Alan Statham: Will you desist? He's a very important man, and you're not to play with his name. No - when is he coming? The Professor.
Boyce: The, er, 21st of Can.
