Kenneth reminded me of the one and ONLY time I got locked out of my truck - I was going home from a new years party, so you can imagine the environment - freezing temps, buzz from the liquid refreshments served that night, and I had to piss! So I pull into a local plants parking lot to get some relief. "I'll just leave the truck running so it will stay warm and shut the door but not latch it..." The d@mn thing latched about half way trough my duties - and my coat was in the truck that was still running! I had to walk up to a local gas station and try to explain to the lady clerk that I was needing to borrow anything she had that had a magnet on it.
At least the D@mn thing was warm when I got back. I can still see the look on the old ladies face when I was trying to explain what had happen and why I was needing a magnet:p
