If, for some strange reason, you don't watch The Great British Bake Off, then this fun little moment will have flown right over your head.
During an early scene in The Vanquishers where Joseph Williamson explains his tunnels to the Doctor, she responds by thanking him for his work, before leaving him with a much-coveted Hollywood handshake.
A Hollywood handshake is essentially the highest form of praise that Bake Off judge Paul Hollywood can bestow upon the contestants, usually being reserved for moments of genuine excellence.
It's a great honour, often leaving the recipient - like good ol' Giuseppe in the most recent series - in tears.
