"Premiering on September 13 of that same year, Late Night with Conan O'Brien received generally unfavorable critical reviews for the first 2 to 3 years after its debut. O'Brien himself, a total unknown among the general public before being named host, was seen by many as not being worthy of the program. NBC even poked fun at this perception in a radio ad which aired shortly before the show's debut and had O'Brien relaying an anecdote where someone recognized him on the street and said, "Look, honey, there's the guy who doesn't deserve his own show!" Another source of criticism was the fact that O'Brien himself appeared to be very nervous and awkward during the show's early days. As a self-deprecating nod to this, the original opening sequence for Late Night With Conan O'Brien was animated and featured a caricature of O'Brien who sweated and pulled at his collar nervously."
