Oh yeah, Maybe 5 years ago? I had a gap between my lease and being able to get into my new place. My friend and his wife were cool and let me stay in their finished basement roughly a month. So on moving day, literally on my last "final check trip" down the steps, I slipped on the top step, grabbed the railing which only spun my around, lost my grip and did the backward somersault into a slide, and ended up grabbing the railing 1 step from the floor.
My buddy's wife came running and was like "OMG are you ok?" I wasn't hurt at all, it was just crazy. Now periodically it'll come up when we're hanging out and we'll laugh about how I was inches away from them having to move because they wouldn't want to live in a haunted death house.
