That is from a BBC Radio 4 comedy called Cabin Pressure, which Benedict Cumberbatch also stars in. The “nice hot cup of coffee” line is from the St. Petersburg episode. There was a time at which they were all available on Youtube, but I believe they’ve been taken down for copyright reasons.
It’s a brilliant radio show, if you should deign to buy it through iTunes or something. You will come for the Benedict, but you will stay for the hilarity.
