Howard Stern on Letterman — his best appearances on ‘Late Night’ and ‘Late Show’

Howard Stern and David Letterman are good friends — or at least it comes off that way on TV.

Over the last thirty years, The King of All Media has made several appearances on David Letterman-hosted talk shows — both the NBC version of Late Night with David Letterman and the CBS variety Late Show with David Letterman. Every time Howard Stern makes an appearance, it’s a spectacle to behold.
