I'm just going through Doctor Who with Christopher Eccleston, and the double episodes of The Empty Child/The Doctor Dances are written by Moffat.
In The Doctor Dances are the following two lines that the Doctor says:
"Funny little human brains. How do you get around in those things?"
"I am on fire!"
Hmmm... paraphrased/repeated later in Sherlock ASIP and TGG.
