it's like Spinal Tap. with a TARDIS.

moral-highground:

David Tennant: WHAT is that sound effect!?

Christian O’Connell: That’s the TARDIS!

DT: That’s not the TARDIS, that’s the sound of a toilet flushing!  Anyway, “AH!  Here I am at the Master’s lair!”

John Simm (over the phone): Hello

DT: Oh, John.. I am so sorry, mate.  I am so sorry to have gotten you into doing this.

JS: -laughs- I thought you were being a DJ….

This is so hilarious.  Poor John Simm.  Poor David Tennant.  Poor everyone.

I remember, last year, listening live and being so excited when he called John. It was quite sad of me, really.
