Was working at a car wash, 16 years old. Three guys I knew pulled in to get their car washed, asked me what I was doing. Said I'm just about off work and have to go home to work on my car (a constant battle with that POS.) They tried to get me to come with them, they had somehow got a bunch of those little single-serving tequilla sunrise bottles. I told them I really couldn't. They left. I heard about an hour later that just about five minutes after leaving the driver was speeding down south Main St, couldn't make a corner by Wildcat Park, and crashed. The driver was instantly killed (partially decapitated.) The front seat passenger got all sorts of injuries including his left foot basically cut off. The guy in the back seat was ejected and broke his back in three places, among other bones. I never saw him again. The front seat dude, I saw him about a month after the wreck and he said they were talking about me missing out on the fun just as they left the road.
That's probably not even the stupidest, actually. Luckiest perhaps.
