- [an RAF doctor is giving Robert yet more tests]
- Squadron Leader Wentworth: Your father gave me a lesson in military etiquette. I shall give you one. I am called "Sir".
- Robert Lawrence: What are you? Squadron Leader? In the Household Division we don't call your rank "Sir".
- Squadron Leader Wentworth: Well you can start now, Lawrence.
- Robert Lawrence: You're in the Royal Air Force. Are you a flyer?
- Squadron Leader Wentworth: No I'm not. I'm a doctor.
- Robert Lawrence: [snarls] Well listen, Doctor. Just test this fist. It's just about to give you your first fucking flying lesson!
