Frahnkensteen

In my opinion, this is one of the best exchanges of dialogue in any movie ever made:

(UNSEEN): "DOCTOR FRANKENSTEIN?"

DOCTOR (coldly): "Frahnkensteen."

IGOR: "You're putting me on."

DOCTOR: "No, it's pronounced 'Frahnkensteen'."

IGOR: "Do you also say, 'Frohderick'?"

DOCTOR: "No, 'Fredrick'."

IGOR: Well, why isn't it 'Frohderick Frahnkensteen'?"

DOCTOR: "It isn't; it's 'Fredrick Frahnkensteen.'"

IGOR: "I see."

DOCTOR: "... You must be Igor."

IGOR: "No, it's pronounced "Eye-gor."

DOCTOR: "But... they told me it was Igor."

IGOR: "Well, they were wrong, then, weren't they?"  (Smirk)

DOCTOR:  "..."

If you haven't seen 'Young Frankenstein', there's something wrong with you.  Or maybe it's me.  But I don't think so.
