The following happened to me once: I found a wallet in a potted plant outside a grocery store. It contained a fair amount of cash plus credit cards, ID, etc. I planned to leave the wallet at the store, but I figured I'd better notify the owner to make sure they got their goods back. The ID was of a female doctor. I looked her up in the phone book and it turned out she was a sex therapist.
Unfortunately that is as exciting as this story gets.
