I'm the postmaster for a small town in Pennsylvania. One of my regular customers, Jeff, bought several sheets of newly released commemorative stamps.

Soon after he left, a woman came in carrying two crisp sheets of Harry Houdini stamps she'd found in the parking lot.

The next morning, I gave Jeff the sheets of stamps he'd lost.  "You know," Jeff said to me, "I'm not at all that surprised the Houdini stamps reappeared."
