CHEKOV: You know this man, Captain?
KIRK: Oh, do I know him. Harcourt Fenton Mudd, thief
MUDD: Come now.
KIRK: Swindler and con man
MUDD: Entrepreneur.
KIRK: Liar and rogue.
MUDD: Did I leave you with that impression?
KIRK: He belongs in jail, which is where I thought I left you, Mudd.
[...]
KIRK: All right, Harry, explain. How did you get here? We left you in custody after that affair on the Rigel mining planet.
MUDD: Yes, well, I organised a technical information service bringing modern industrial techniques to backward planets, making available certain valuable patents to struggling young civilisations throughout the galaxy.
KIRK: Did you pay royalties to the owners of those patents?
MUDD: Well, actually, Kirk, as a defender of the free enterprise system, I found myself in a rather ambiguous conflict as a matter of principle.
SPOCK: He did not pay royalties.
MUDD: Knowledge, sir, should be free to all.
KIRK: Who caught you?
MUDD: That, sir, is an outrageous assumption.
KIRK: Yes. Who caught you?
[...]
MUDD: The key word in your entire peroration, Mister Spock, was, death. Barbarians. Well, of course, I left.
KIRK: He broke jail.
MUDD: I borrowed transportation.
KIRK: He stole a spaceship.
MUDD: The patrol reacted in a hostile manner.
KIRK: They fired at him.
MUDD: They've no respect for private property. They damaged the bloody spaceship. Well, I got away, but I couldn't navigate, so I wandered out through unmapped space, and here I found Mudd.
