I was amused to read, today, that a French guy went to hospital with a World War 1 shell, 16x4cm, lodged up his ass! It caused the temporary closure of the hospital, and the attendance of the Bomb Squad! The shell, and the guy, were safely defused. A rather advanced form of Russian Roulette, perhaps? One reads of unusual insertions, but I thought this takes the biscuit, so to speak. Entertainingly, the guy may be charged under French weapons legislation. Interesting to speculate what the charge (sic) might be!
