The Germans

With Sybil in the hospital with an ingrowing toenail, a moose's head to hang up and some German guests arriving the next day, Basil has his work cut out for him. After an attempted fire drill goes wrong and Basil lands up in the hospital with concussion, he succeeds causing much offense to the German guests after finally escaping back to the hotel. This episode is the origin of the quote "Don't mention the war."
