In what episode(s) do the lines “Doctor Who?” “If you like” occur?

Question

I was curious if someone could help me remember which Doctor had this exchange in the new series... I can't remember the Doctor (though I think it was the 11th) or episode.

THE DOCTOR: I'm the Doctor!

[UNKNOWN]: Doctor Who?

THE DOCTOR: If ya like!

It was very snappy comedic timing. I'd greatly appreciate the help.

Answer 1

The only example off the top of my head is the Season 7 episode "Hide", when Clara and the Doctor enter the "haunted" house we get this exchange:

The Doctor: Hello, I'm the Doctor.

Professor Palmer: Doctor what?

The Doctor: If you like. [Proceeds to do Doctor-y things]

And you're right, this is the Eleventh Doctor.

Answer 2

That would be "Hide" from series 7, but the line is “Doctor what?”.
