JAMES CORDEN: Oh no Sherlock the Detective has died, and I saw him explode and the individual fragments of his face fly off into every one of the compass directions
PETER CAPALDI: Oh did I really
JAMES CORDEN: But how did you do that?
PETER CAPALDI: I decided that I would come back to life

PETER CAPALDI: Now that I solved the mystery by coming back to life. I'm going to have a nice wee in the toilet
JAMES CORDEN: You've earned it, pal
PETER CAPALDI is weeing in the toilet, when suddenly he notices that the rhythm formed by the impact of his urinary output on the water that resides within the toilet says "MISS ME?" in morse code
PETER CAPALDI: Moriarty! He's in my bladder of course.
JAMES CORDEN: Gah! The cad was right under yer nose the whole time
PETER CAPALDI: Not quite, Clara! He was just under my kidneys
