The subplot involving Tracy and Kenneth telling jokes in the elevator is based on Tracy Morgan doing the same thing, as he would do some of his stand-up act in the elevator to make people laugh. The bit about why there are no Puerto Ricans on Star Trek (1966) is from actual stand-up act.
Liz Lemon's phrase "I want to go to there" (which she says twice in this episode) was originated by Tina Fey's daughter Alice when she was young.
The episode won an Emmy Award for Outstanding Writing for a Comedy Series.
When Jack and Liz are in the closet during "Seven Minutes In Heaven", Jack says that kissing Liz would be "social suicide," a call-out to the phrase popularized in Mean Girls (2004), which Tina Fey wrote and starred in.
Throughout the scene where the group approaches Jack thinking he's a former classmate, his "Larry Braverman" name tag keeps appearing and disappearing.
