The guy playing the paramedic went on to play a paramedic in ER for many years. On the same topic, Maura Tierney (Lisa Miller) also joined ER and stayed for 9 years as Nurse/Doctor Abby Lockhart.
I read an interview Maura Tierney (Lisa Miller) gave and when asked who should play her in her life story she said Dave Foley because he is funny and looks great in a dress.
In an interview Phil Hartman said he was just trying to quit smoking when this episode was shot, making it that much more difficult. He also claimed that many of the cast and crew were smokers, which only added to his troubles trying to quit smoking.
