Locking Out the KGB
RAY: So the question is how do you package your valuable objects so that the KGB cannot open it, but your friend can? Now instead of a key, I would have mailed a hacksaw. But in the spirit of the puzzler that wouldn't have been fair.
RAY: You put the valuable thing in the box. You put as many locks as you want on the clasp, making sure you leave room for at least one more.
RAY: You mail the thing to Russia. Your friend gets it. He doesn't have a key to any of these locks that you put on it. He puts another lock on it for which he has the key. He mails it back to you. You remove all of your locks and you can't get it open now. But you don't have to.
TOM: He can.
RAY: When you mail it back to him.
RAY: Do we have a winner?
TOM: We do, and that's a good one, man. I like it. Yeah, the winner is Melissa Metzger from Las Vegas, Nevada. And for having her answer selected at random from among the slag heap of correct answers that we got, Melissa is going to get a 26-dollar gift certificate to the Shameless Commerce Division at cartalk.com, with which she can get a set of CDs with four of our favorite shows on them, called Four Perfectly Good Hours.
RAY: Gee, of all the shows we've done, all you could come up with more than four.
TOM: That's all we got, that's it. Congratulations Melissa!
