Stepping into the late-late slot vacated by David Letterman, Conan O'Brien stars in a show that far outdoes its competition in sheer strangeness. Along with the celebrity interviews and musical numbers typical of late-night talk shows, this program make frequent use of odd walk-on characters and frequent "visits" from celebrity guests.
