We had one DM who had a pre-agreed to rule that if you weren't there, or if you had to leave during a session, your character fell unconscious right where he was, no matter what was happening, and it was the responsibility of the other PCs to take care of that character. This was pretty easily explainable, as there was an evil mystical event that was going on in the world at the time which was turning everyone into undead of various sorts. So when a character fell unconscious, it was explained as the undeath curse trying to murderate the character, and the character having to expend all of his energy fighting it off...
Well, one day, we were in the middle of a combat that was taking considerably longer than anyone had guessed or intended it to take. One of the players had to go to work... so he did. His character, predictably, fell out... right in the middle of the fight (we were fighting some demon-tigers). That was okay, though. Things were going fine, and we had the demon-tigers on the run (the two remaining of the five original critters took off in the round after the character fell out).
Because we were pretty torked off at these critters (I believe that they had been stalking us for a few days, making hit and run attacks, etc... before this) and because we weren't thinking... at all... we gave chase. Well demon-tigers are faster than people, and one of them managed to get away from us in the jungle. So... we trekked off back to where our good friend (remember him?) lay inconscious and helpless.
Lo and behold (of course) he was nowhere to be found when we got back to where we had left him. The remaining demon-tiger had circled around and dragged him off while we were chasing him and his buddy through the jungle. Fortunately, our unconscious comrade was pretty heavy, and that slowed the demon-tiger down enough so that by the time we found him and his tasty snack (our comrade), he was only partially eaten, and was, miraculously, still alive, though missing a leg.
It was about fifteen sessions after that, that we finally reached a level where someone could cast regenerate on him...
