A small-screen heavyweight since the debut of Late Night With David Letterman back in 1982, funnyman David Letterman is still going strong as the wisecracking host of this, one of the most popular late-night talk shows on television. Longtime sidekick Paul Shaffer leads the studio band as A-list celebrities, Z-list celebrities, side-splitting comedy sketches, and Letterman's trademark Top 10 List keeps viewers laughing through the midnight hour. ~ Jason Buchanan, Rovi
