Comedian/writer Carol Leifer plays Wendy's (Wendie Malick) receptionist in this episode and said during the scene where George (Jason Alexander) is signing a check to pay for his appointment, he wrote obscene messages to her during every take.
This is the first time in the series the audience gets to see the lobby area of Jerry's (Seinfeld) apartment building.
Although this was the 103rd episode to air, the cast and crew of the series credit this as the 100th episode because it is the 100th episode created.
Kramer (Michael Richards) likes the idea of everyone who lives in the building knowing each other's names but this was not always the case. In episode 5.7, The Non-Fat Yogurt (1993), he ridicules New Yorkers who wear name tags for that very same reason.
Several times, George insultingly refers to Wendy as a "Delicate Genius," a term which has become a notable Seinfeld catchphrase.
