Hogan impersonates General von Himmelberger of the German General's Staff.
Throughout the episode, the DuBois character is called Henry, but in the closing credits his first name is Emil.
Carter is asked to tutor LeBeau in rudimentary chemistry, yet allows that, while running a pre-war pharmacy in Muncie, Indiana, he knows very little about chemistry.
Klink: The man who invented hemolac can't even remember his own serial number.
Hogan: They're all that way. Einstein once left the house without his pants.
Klink: That means nothing to me.
Hogan: Meant something to him.
Hogan: He who dances must pay the fiddler.
Schultz: Who's dancing?
Hogan: Colonel, you worry too much.
Klink: I worry? Huh. Your life is easy. You're only a prisoner of war.
Hogan: Didn't you learn anything from DuBois?
LeBeau: Well, most of the time we just made crepes suzettes.
Hogan: (as von Himmelburger) I want this girl brought down and put in my machine in five minutes! (smashing plates and glasses) Repeat, five mintues! (smashing) If you do not follow my orders within that time (smashing) you will all be transferred to the Russian front! Including the hotel itself!
Hogan: If a general showed up at the Hausner Hof and demanded the girl...
Newkirk: Where are we gonna get somebody like that? He comes up with ideas...
Hogan: (in German accent with coin as a monocle) You will stand at attention when General von Himmelburger addresses you!
Schultz: (enters scene) Jawhol, Herr Gener...
(Hogan salutes, Schultz realizes his mistake and leaves)
Hogan: You have never heard of Louis Lebeau? The man they call 'Mr. Test Tube' at the Ecole de Chemie in Paris?
Klink: He's a chemist?
Hogan: In France, he's known for the discovery of hemolac!
Klink: He...hemolac? What is hemolac?!
Hogan: That's a problem for after the war: What is hemolac?

The prisoners' bright-red coffee pot is replaced by one of a duller color in this episode. This may have been changed due to distracting views in previous episodes.
The first allusion that Klink's living quarters are attached to his office as he is dressed in his robe coming through a door by the secretary's office ... just to note - in the coming seasons, that door is almost never used.
