The Professor quotes from North by Northwest (1959)

The Professor

We do nothing...That's right, nothing. Oh, we could congratulate ourselves on a marvelous stroke of good fortune. Our non-existent decoy George Kaplan created to divert suspicion from our actual agent has fortituously become a live decoy... What can we do to save him, without endangering our own agent?...We didn't invent our non-existent man and give him the name of George Kaplan, establish elaborate behavior patterns for him, move his prop belongings in and out of hotel rooms for our own private amusement. We created George Kaplan and labored successfully to convince Vandamm that this was our own agent hot on his trail for a desperately important reason...If we make the slightest move to suggest that there is no such agent as George Kaplan, give any hint to Vandamm that he's pursuing a decoy instead of our own agent, then our agent working right under Vandamm's very nose will immediately face suspicion, exposure and assassination, like the two others who went before.

You're police, aren't you? Or is it FBI?

The Professor

FBI, CIA, ONI... we're all in the same alphabet soup.
...

The Professor

Oh, you could say he is a sort of importer/exporter.

Roger

Of what?

The Professor

Oh, government secrets perhaps.

The Professor

If I thought there was any chance of changing your mind, I'd talk about Miss Kendall, of whom you so obviously disapprove.

Roger

Yes, for using sex like some people use a fly swatter.

Roger

I don't like the games you play, Professor.

The Professor

War is hell, Mr. Thornhill, even when it's a cold one.

Roger

If you fellas can't lick the Vandamms of this world, without asking girls like her to bed down with him and fly away with him and probably never come back, perhaps you ought to start learning how to lose a few cold wars!

The Professor

I'm afraid we're already doing that.
