Welcome to the Letterman YouTube Channel, home to all your favorite clips from Late Night and Late Show - as well as conversations with the writers, producers and performers who helped make it all happen. These highlights have been artisanly-produced, carefully-curated, and chosen completely at random by an old computer that used to pick numbers for the New York Lotto back in the 90’s.
