Young Frankenstein (1974)

Inga: Dr. Fronkensteen! Are you all right?
Fredrick Frankenstein: MY NAME...IS FRANKENSTEIN!

Dr. Frederick Frankenstein: You know, I'm a rather brilliant surgeon. Perhaps I can help you with that hump.
Igor: What hump?

[A wolf is heard howling in the distance.]
Inga: Werewolf.
Frederick: Werewolf?
Igor: There.
Frederick: What?
Igor: [Points to moors] There wolf. [Points forward] There castle.
Frederick: Why are you talking like that?
Igor: I though you wanted to.
Frederick: No, I don't want to.
Igor: Suit yourself. I'm easy.

Student: What about your grandfathers' work, sir?
Fredrick Frankenstein: MY GRANDFATHERS' WORK WAS DOO-DOO! I AM NOT INTERESTED IN DEATH! THE ONLY THING THAT CONCERNS ME IS THE PRESERVATION OF LIFE! [Stabs himself in leg with a scalpel.] Class...is dismissed.

Frankenstein: Damn your eyes!
Igor: Too late.

Igor: You know, I'll never forget my old dad. When these things would happen to him... The things he'd say to me.
Dr. Frederick Frankenstein: What did he say?
Igor: "What the hell are you doing in the bathroom day and night? Why don't you get out of there and give someone else a chance?"

Inga: Hello. Would you like to have a roll in the hay?

Dr. Frederick Frankenstein: For what we are about to see next, we must enter quietly into the realm of genius.

Frederick Frankenstein: Igor, would you give me hand with the bags?
Igor: Certainly. You take the blonde and I'll take the one in the turban.

Igor: Two nasty lookin' switches over there, but I'm not going to be the first.

Dr. Frederick Frankenstein: From that fateful day when stinking bits of slime first crawled from the sea and shouted to the cold stars, "I am man.", our greatest dread has always been the knowledge of our mortality. But tonight, we shall hurl the gauntlet of science into the frightful face of death itself. Tonight, we shall ascend into the heavens. We shall mock the earthquake. We shall command the thunders, and penetrate into the very womb of impervious nature herself.

Igor: Wait, master, it might be dangerous... You go first.

Igor: My grandfather used to work for your grandfather. Of course the rates have gone up.
