Johnny Dark Insults David Letterman, goes nuts with hooker ideas and Twisting

A very vivid encounter between Dave and "the oldest CBS page" Johnny Dark, from 2005. The humor IS a bit Dark (even though Johnny's real last name is not Dark...it's Koletes). The insults and glowering is quite different from the impressions and comedy bits Johnny did years earlier in live stand-up and on the "Donny and Marie" show. Dave was such a fan, Johnny did about 50 cameo appearances on the show. And yes, Paul, we get the music you play as he walks out...Bob Dylan's "My Back Pages."
