Reminds me of another one (terrible autobiographical memory!). I'd had a few lessons at a classical equitation yard not far from me and was very wowed by all the canter piris and piaffes (proper ones) going on, so was thrilled to be asked if I wanted to get some riding in exchange for help. First time I did this it was a foul winter day and the two pro riders were taking no prisoners in the little school so I just tried to keep out of the way while doing something useful on my horse. I was then asked to swap on to a different horse. Went to swing leg over to dismount. It was a very deep dressage saddle with an insanely high cantle. Got leg stuck. Other leg was out of stirrup and on the way down (never did learn the keeping one foot in the iron as you step over). In front of agog audience of trainer and two perfect 20-something riders I did the splits very ungracefully under the belly of the very patient school horse and just managed to cling on to something long enough to free the errant leg and not end up sitting in soggy sand/rubber. Fiery embarrassment. However I did survive that and spent several years there until I had to stop riding, and learnt so much in the process.
