Kathy Knapp previewed: I just saw a preview for the David Letterman show for tonight, later on CBS - he is to have an Origami Challenge. All I saw was the wording written as if it were folded, and heard the words, which made me look up to see the screen.

After 30 seconds, he produces a well-made frog, but fails the challenge. I don't know if any other origami happens during the rest of the episode. I'll report when I finish watching. Faye
