Randee Heller was nominated for Outstanding Guest Actress in a Drama Series at the Emmys for her performance in this episode.
In the beginning of the episode Stan sings the song "Downtown" to Peggy. It's the same song that Winona Ryder and Angelina Jolie sang to Elisabeth Moss character in the movie Girl, Interrupted (1999) to calm her down after crying and screaming. (However, he's singing the song to goad Peggy's lesbian friend, having to do with the words "Going Down")
