I'm embarrassed already, I hit the wrong button. Anyway, Sydney 1970, three sailors - me one of 'em. Lots of beer, find some girls, find a party. Passion time, engaged in activity with tongue fully extended. All okay until the fine membrane of skin on the bottom side of tongue slips down into gap in front teeth and gets caught there ! Cannot retract tongue into mouth - very painful. Girl puzzled to say the least, thinks I'm just fooling around. It's very difficult to be coherent with one's tongue hanging out of the mouth, try it, just a lot of slobber & dribble. Found one of the mates who organised a taxi for us to an all-night chemist. The taxi driver was pretty chary, guess he'd never had a passenger before who kept his tongue out for the whole trip. The chemist put a small clamp on my teeth and opened the gap, the membrane slipped out, and tongue retracted. Joy of joys ! The muscles at the back of my throat ached for days. The mates ribbed me for years. It's funny though, when you fall off a horse .................
