Continuity: In this episode, George asks Russell if his last name contains a "y" and Russel answers that it doesn't. However, Russel is credited in this and subsequent episodes as "Russell Dalrymple."

Other: When Kramer is modeling underwear for the Calvin Klein people, he leans and slides against a wall leaving a large spot of body makeup.

Factual error: George's mother says when she was reading about George being gay, she fell off the toilet, and the superintendent had to help her. Well, the Costanzas live in a private house, and thus have no superintendent.

Factual error: Kramer gives Jerry a two-line phone for his birthday, which Jerry plugs in and immediately uses. But a two-line phone requires the installation of an actual additional phone line. What Jerry was using when the NYU reporter overheard him "admitting" he was gay was simply call-waiting.

Continuity: When "Mulva" is giving Jerry a neck massage, check out the bathroom door in the background. It keeps changing from open to closed.
