I've not really had any mishaps while drunk, unfortunately most of mine happen when I'm sober. I have had a friend break my toe before though, similar to PoT's story. We were at a friends house and everyone was barefoot except one girl in boots who kicked my little toe somehow. I was quite drunk at the time so I don't recall it hurting too much. When I woke up the next day though it was painful and bruised a good few cm down my foot, on the top, side and sole of my foot. It was pretty impressive. Luckily i was a uni student at the time so didn't have to wear closed in shoes too often (except for a couple of days a week when I was at work).
