After I left high school I signed up with a temp agency, filled out all the paperwork, never heard anything. Twelve years later, I received a phone call. I explained I had been employed full time for over a decade. They said that if I refused the assignment I might not be eligible for future opportunities. I told them I was ok with that. ;)

Along the same vein, a few years ago I had an employer that wanted proof I graduated high school. Blink. "You realize that I graduated almost forty years ago?" Didn't matter. Believe it or not I actually found the school system and they were able to produce a copy. I'm sure they had to climb over Jimmy Hoffa's cryotube and the Ark of the Covenant to get to it.
