Many, many moons ago, I got a middle of the night phone call from a friend who said "I'm in jail. They'll let me go if you come get me."
Except he didn't tell me WHICH jail he was in.
I checked the city lockup, and the county building, but they didn't have him.
He did finally get out, and when I told him about it, he admitted he was in another city and, at the time, wasn't even sure where he was.
The best part was his motorcycle was still in ANOTHER town, and it took him a week to find it.
