Submarine Toilets

You couldn't use the loot when you were anywhere near the enemy. It was feared that using the toilet would make such a loud noise of clanking metal, and then it would cause floating debris to appear outside your submarine. They had frequent singing, limerick, in and lying competitions,. apparently lying as in telling lies. Or just being prostrate. Underneath their bunks were torpedoes at the beginning of the voyage, because there was just no space. Life on board submarines wasn't fun but they do have fun sometimes.
