I was once on an excursion down the Clyde on the restored paddle steamer "Waverley" with a whole family of people like Extrovert Woman. It turned out they were an American officer from the nuclear megadeath base at Holy Loch and his family. After about three hours of loudmouthed inane commentary and Reaganite whining from Lootnant Megadeath, Mrs Megadeath and the three little Megadeaths, the thought that the whole firth was multi-targeted by Soviet ICBMs was kinda comforting. As it happened the Lootnant got a different kind of pre-emptive strike, from a very large seagull that must have been constipated for a month before letting go directly over his head.
