- Danny: I'm a maths teacher.
The Doctor: But what about all the PE?
Danny: I don't teach PE. I'm not a PE teacher.
The Doctor: Sorry, that seems very unlikely.
Clara: Er, excuse me, Mr. Pink, I think the class are waiting.
The Doctor: Yes, you better run along, Sergeant. That ball isn't going to kick itself, is it?
Danny: I'm not a PE teacher, I'm a maths teacher.
The Doctor: Nope, sorry. No, I can't retain that. I've tried. It's just not going in.
Plenty comfy. Won the BAFTA for greatest soap opera of 2014.
