30 Rock

Liz Lemon is the head writer on a demanding, live TV program in New York City. However, things begin to get complicated when her new boss insists that a wild and unpredictable movie star joins the cast.This episode was pretty similar to the one that aired, with only some differences in terms of the direction of the show. Perhaps the most notable difference is the fact that Rachel Dratch had a starring role, from which she was replaced due to creative reasons and given different recurring roles.

On show night, Liz Lemon grows increasingly infuriated when no one seems to remember that it's her 40th birthday. Just before the taping, Tracy Jordan becomes convinced that nothing is funnier than a performer laughing and breaking character, which he elects to do all night, much to Jenna Maroney's chagrin. Meanwhile, Jack Donaghy struggles with the consequences of his promise to give up drinking while Avery is pregnant. The episode was filmed twice. The East Coast version aired for the Eastern, Central and Mountain time zones. The West Coast version was aired in the western, Alaskan and Hawaiian time zones.

Kenneth takes drastic measures to prove why TGS should stay a live show. When their Kabletown bosses announce they will no longer pay for TGS to be a live show, Liz Lemon and Jack Donaghy realize their lives will actually be easier if they shoot canned episodes fast and cheap. Only Kenneth the page objects, urging that nothing can replace the communal experience of live television. He tries to convince the TGS staff to fight for their right to be live by taking them and our audience through a magical look back at the illustrious history of Studio 6H. The episode was filmed twice. The East Coast version aired for the Eastern, Central and Mountain time zones. The West Coast version was aired in the western, Alaskan and Hawaiian time zones.

Jenna's Obituary Song

Losing one of the two Jon Hamm appearances in one thing, but if the east coast gets Paul McCartney and the west coast gets Kim Kardashian, then the west coast got hosed. (Watch the end to see how ill-equipped she is for the simple act of delivering a punchline.)
