There was a story concerning The Abandoned Earl - Air Marshal the Earl of Bandon - many moons ago.
He was visiting a V-bomber base and, at the associated dining-in night, threw himself enthusiastically into the post-dinner festivities. After several beers he wandered out for a pee. Most 1930's style messes have an identical layout, but, over time, the sanitary facilities tend to get moved about. The Air Marshal searched for the appropriate place, without success, and eventually, hydraulic pressures being what they were, he dived into a cabin and peed into the washbasin. The astonished occupier woke up and essayed a cautious "Good evening, Sir".
The Earl zipped himself up, stared down at the officer and said "Good God, some people will sleep anywhere!".
