I was home on leave from the Army one year. I got drunk and passed out in a field about half a mile from my foster parent's house. Sometime during that drunken night I lost my wallet (which was one of those nylon camouflage-pattern ones). Well, that sucked ass, had to get all of my ID replaced and stuff.

Well, a year later I came home on leave again. I got drunk, passed out in the same field (it was a handy field to pass out in!). In the morning, all hung over, I felt something digging into my side, so I rolled over to see what it was and...it was my wallet! I couldn't believe it, it was just such a weird coincidence, and not only was it there, but it was pretty much intact. I eventually did totally lose that wallet last year when my home burned down, but that wallet lasted me 22 years!
