At one point, a hospital worker is remarking about a bullet hole he is patching up. Given the location, this is probably referencing the event seen in Cora and Arnie.
Craig: Sometimes, I fear I'm not too liked around here. Oh now, Donald, it's all right. I'm not out to win any popularity contests. The work what's important, not the recognition...
Westphall: Absolutely right.
Crig: ....even though I shoulda won last year.
Skilling: My, my, the monsters our children have become! Remember your roots, Doctor Chandler. It was not too long ago the cotton you were picking wasn't from an aspirin bottle!
Fiscus: (looking around hospital mortuary) It's hard to be comfortable in a room where everybody else is so stiff.
Ehrlich: Hey, I'm sorry I'm late.
Fiscus: Well, I guess you didn't hear then.
Ehrlich: Hear? Hear what?
Fiscus: They recalled your class at Brookline Memorial. Instead of teaching you anatomy, they gave you a course on home heating. The bus leaves for the West Coast about nine o'clock.
Samuels: Yeah, next thing you're going to want to know how to pick up girls. Right?
Kid: That's easy. You tell them what they want to hear.
(Nurse Rosenthal throws a disapproving glance at Samuels)
Samuels: I didn't teach him that. I swear. It's intuitive.
In the scene towards the end of the episode where Dr. Samuels speaks with a woman in a bar, "More Than a Feeling" by Boston plays in the background. However, the song was replaced on the DVD version.
This episode marks the first appearance of Ellen Craig, wife of Dr. Mark Craig played by Bonnie Bartlett (who is incidentally the real life wife of William Daniels).
G.W. Bailey does not appear in this episode.
Nurse Daniels: So, Fiscus. How's the Affair to Remember?
Teasing Fiscus about his infatuation with Cathy Martin, Daniels references An Affair to Remember (1957), considered one of the romantic movies of all time. Starring Cary Grant and Deborah Kerr, the movie tells the story of two strangers who fall in love on a cruise and then agree to reunite at the Empire State Building six months later. The movie is also serves as a romantic touchstone in the 1993 movie Sleepless in Seattle.
Fiscus: I saw a Twilight Zone once where a little girl rolls under her bed, through a wall into another dimension of space and time.
The Twilight Zone (1959-1965) is one of the world's most celebrated television shows. Created and hosted by Rod Serling, the program was an anthology series featuring self contained stories of sci fi, fantasy and horror. The particular episode Fiscus recalls is Little Girl Lost (3/16/62)written by Richard Matheson. The episode also served as the inspiration for the 1982 motion picture Poltergeist.
