Trivia: Kenneth and Jack compare giving a tour of the station to Willy Wonka. Later as Kenneth and track are actually giving the tour we see the guests, which all match characters from Charlie and the Chocolate Factory. One is overweight and has a German accent like Augustus Gloop, one woman is wearing a red dress reminiscent of Veruca Salt, one is wearing a bolo tie like Mike TeeVee, one is very similar to Violet Beauregard. And finally one is seemingly pure of heart and clean cut like Charlie Bucket.
Trivia: Season 3, Episode 11, "St. Valentine's Day". When Jack is in the church confessional, he tells the priest that one of his sins was "I once said I was God in a deposition." This is a reference to Alec Baldwin's character in "Malice", where he did state he was a God during a deposition.
Trivia: Jack mentions that Jonathan was able to come back to 30 Rock because "the grass was not greener on the other side." This was a subtle shot at the show Weeds. The actor playing Jonathan (Maulik Pancholy) was on that show, which was about selling marijuana (grass). When Weeds was canceled, Pancholy came back to resume his role on 30 Rock.
Trivia: Rachel Dratch was originally going to play Jenna, and in fact even appeared in the original unaired pilot. Her Jenna would have been an entirely different character - much more sweet and even-tempered. However, Tina Fey decided to rewrite the character as much more vain and spoiled, and felt Dratch no longer suited the part. Thus Jane Krakowski ended up being cast to replace her.
