Yea, right. I was born at night, but NOT last night.

Now...where'd I put that tin foil?

Frequently a bomber will put his or her name and address on the cover. The guy who almost nailed me was picked up in less than an hour.

I would imagine there's the same sort of circumstance here ~ a return address with the guilty party's name.
