Revealing mistake: In an early episode Jack introduces Tracey to all the TGS writers, but giving mini bios and facts about them in rapid Succession. Seconds later we go to a flashback of Jack's assistant holding up pictures of random people as Jack names them. The problem though is you can see that it's the same picture being used every time.

30 Rock (2006)
1 revealing mistake - chronological order
Starring: Alec Baldwin, Tina Fey, Tracy Morgan, Jack McBrayer, Scott Adsit
Genres: Comedy
Character mistake: Tina Fey fumbles her line and has to start it again. The original line should have been "How long do you think you're going to get away with this? Hazel or Jenna will know we're missing." Instead the second part of the line is "Henna or Jay; Hazel or Jenna will know we're missing!" (00:04:05)
Trivia: When Cooter (Matthew Broderick) and Jack are looking through all the files to find a bad idea it's very reminiscent of Matthew Broderick and Nathan Lane as Bialistock and Bloom looking for bad scripts in The Producers. Yet another musical theatre nod by a writer.
Question: Why does Liz put up with all the craziness? She couldn't quit and work on another show?





Answer: There's probably lots of reasons why Liz stays - money, lack of other job prospects and so on. The reality is, if she left, that would adversely affect the story line and the comedy within it. Tina Fey was one of the stars, and her character is an integral part of the show.

Yeah, she was integral all right. She had and still doesn't have any talent at all. She's rude, an in-your-face about it liberal, which I consider annoying as all get out, not to mention she seems to be as dumb as all get out about anything political. Where'd she graduate, the U of Dummies or U of Snobs?
