30 Rock (2006)

"Tracy Does Conan," Season 1, Episode 7 Tracy is booked on Conan O'Brien's show and everything that can go wrong backstage does, with Conan playing himself in the middle of it. This is the season one episode for anyone who wants pure chaos: Tracy at his most unmanageable, Liz scrambling to hold a TV appearance together and Jack treating the crisis as beneath him. Short scenes, constant interruptions and no wasted beat make it the clearest early sample of the show's speed.
