Going to hijack this thread for my own morbid story...
On Saturday I was at the gig of a friend's brother's band; they're a pretty big-name mainstream act so it wasn't the kind of event where one expects bad things to happen. Anyway, I was on the dancefloor enjoying myself when I suddenly notice a load of guys in high-vis jackets standing a few metres away. They bring in a stretcher and put someone on it and wheel him out; I figure he's fainted or something and carry on enjoying the show. Then shortly after they finish playing a load of us are hanging round the bar when the venue's staff comes in and ushers us all out. Pretty unusual, we're standing outside wondering what's going on when someone says they heard that someone died.
The following evening I'm relating this story to a friend who's an undertaker, and he asks what colour the stretcher was. I tell him it was black, and he replies that that was a coroner's stretcher. So it turns out that I'd watched a corpse being carried off the dancefloor and been completely oblivious to the fact.
