Drunken system recovery
Those stories are the best. In fact, many many moons ago I won a competition run by El Reg where a sysadmin story involving being too drunk to drive but having a set of recent backup tapes in my possession made for a kind of Christmas miracle. I think the star in the sky was a copy of Solaris. A great many very drunken hugs and "man, I love you"s were exchanged that night.
In retrospect, trusting an obviously drunk person to accurate distinguish between tar xvf and tar cvf when X and C are right next to one another on the keyboard might not have been the smartest management decision.
