after some extensive research I have come to the conclusion that David Mitchell is a T-Rex.
I suppose this explains how Charlie Brooker knows how a T-Rex wanks:
Charlie Brooker: The original CSI is set in Las Vegas and it stars a black me who spends his time studying corpses and desperately approaching women in the street.
no, really. i cannot unseen this.
Charlie Brooker: Sorry, I just took a big swig (of whiskey), it’s really strong.
David Mitchell: I’m sorry, I don’t want the show to, in any way, interrupt your drinking.
