Last summer, dead tired after getting off work, got the bike into the garage, got off intending to put it on the center stand, lost balance, fell over with me under the bike, cushioning it, luckily. No damage, no injury, plenty of embarassment when I had to yell to the teenagers shooting baskets in the alley to come and pull it off me.
Lesson learned: Extend the side stand before getting off it.
Years ago: Came out of a bar dead drunk, couldn't start my CB450, kept dropping it, finally got a cab home. I'd accidentally hit the kill switch, probably saved my life.
I don't drink much anymore, and I don't miss it.
