Conan’s skeleton show: trick or treat?

The Halloween edition of Late Night With Conan O’Brien will be broadcast in something called “skelevision,” with an episode from May reconstructed to make the participants appear as skeleton puppets. Wags have asked: How would viewers tell a “skelevision” version of Larry King (who is one of the guests) from the genuine article—or Conan for that matter? But we would never stoop so low. Maybe NBC could work the same trick on the commercials.
