The Doctor: All I've got to is pass as an ordinary human being. Simple. What could possibly go wrong?
Amy: Have you seen you?
The Doctor: So you're just going to be snide? No helpful hints?
Amy: Hmm. Well, here's one... Bow tie, get rid!
The Doctor: Bow ties are cool. Come on, Amy. I'm a normal bloke. Tell me what normal blokes do.
Amy: They watch telly, they play football, they go down the pub.
The Doctor: I could do those things. I don't, but I could.
