i remember watching an episode of conan before where john tesh guested, after years of being conan's butt of all insults -- much like dr. phil's guesting on dave. and it was a prett good show. john tesh was very good natured and conan was on his best behavior.
another guest i love seeing on dave is richard simmons. thinking about him now makes me giggle in front of my computer screen.
like is said, it's all in good fun... and these celebrities know it ain't anything personal.
one leno segment i couldn't stand was when he'd have this huge head and start insulting audience members for being so dumb. poorly written and very unfunny. some are even painful to watch.
i miss my conan tuloy. no more weekends with my favorite carrot top
