ok this one doesn't give Nick's much of a run, but it's still not bad.
A few years ago, I was coming home late from a softball game.  It was a weeknight, and about 11:30pm.  Most everyone on my street were already asleep.
Back then I had the little Mercedes which I was driving home.  Since my Golf was parked where I needed to go, I parked the SLK on one side of the driveway and proceeded to move the Golf into the street.  I park the Golf, and hop back into the Mercedes (the top was down).
As I start to move into the driveway, I notice out of the corner of my eye that the Golf isn't where I put it.  It was rolling slowing (but gaining speed) down the street.  My whole body kinda lurched a bit in my seat, as if I could do something about it but impossibly I couldn't.  So I sat there and watched my car roll down the crescent before smashing into the neighbour's mini-van which was parked in the street.
Turns out I (for whatever reason) left the Golf in neutral without the hand brake on.
Since my neighbour was asleep I never told him.  No I'm kidding.  I went to see him first thing in the morning.  Insurance covered the damage.
