Letterman Pays Special Tribute to Carson

How cool is this. During Monday’s show, David Letterman’s monologue was comprised entirely of jokes Johnny Carson secretly sent him over the past few months. Letterman didn’t tell the audience until after the monologue.

UPDATE: You can watch a clip segment of Carson’s appearances on Letterman over the years on Dave’s site today by clicking on "Big Show Highlight."
