Young Frankenstein (1974)
Medical Student: Isn't it true that Darwin preserved a piece of vermicelli in a glass case until, by some extrordinary means, it actually began to move with voluntary motion?
Dr. Frederick Frankenstein: Are you speaking of the worm or the spaghetti?
[the class laughs]
Medical Student: Why, the worm, sir.
Dr. Frederick Frankenstein: Yes, I did read something of that incident when I was a student, but you have to remember that a worm... with very few exceptions... is not a human being.
Medical Student: But wasn't that the whole basis of your grandfather's work? The reanimation of dead tissue?
Dr. Frederick Frankenstein: My grandfather was a very sick man.
Medical Student: But as a Fronkensteen, aren't you the least bit curious about it? Doesn't the bringing back to life what was once dead hold any intrigue to you?
Dr. Frederick Frankenstein: You are talking about the nonsensical ravings of a lunatic mind! Dead is dead!
Medical Student: But look at what has been done with hearts and kidneys...
Dr. Frederick Frankenstein: Hearts and kidneys are tinker toys! I am talking about the central nervous system!
