Every line from Monty Python and the Holy Grail but here's a fav:
King Arthur: Well I am king.
Dennis: Oh, king eh? Very nice. And how'd you get that, eh? By exploiting the workers. By hanging on to outdated imperialist dogma which perpetuates the economic and social differences in our society.
King Arthur: I am your king.
Woman: Well I didn't vote for you.
King Arthur: You don't vote for kings.
Woman: Well how'd you become king then?
[Angelic music plays... ]
King Arthur: The Lady of the Lake, her arm clad in the purest shimmering samite held aloft Excalibur from the bosom of the water, signifying by divine providence that I, Arthur, was to carry Excalibur. THAT is why I am your king.
Dennis: [interrupting] Listen, strange women lyin' in ponds distributin' swords is no basis for a system of government. Supreme executive power derives from a mandate from the masses, not from some farcical aquatic ceremony.
and Mel Brook's Young Frankenstein:
Frau Blücher: Would the doctor care for a... brandy before retiring?
Dr. Frederick Frankenstein: No. Thank you.
Frau Blücher: [suggestively] Some varm milk... perhaps?
Dr. Frederick Frankenstein: No... thank you very much. No thanks.
Frau Blücher: [suggestively] Ovaltine?
Dr. Frederick Frankenstein: NOTHING! Thank you! I'm a little - tired!
Frau Blücher: Then I vill say... goodnight, Herr Doctor.
Dr. Frederick Frankenstein: Goodnight, Frau Blücher.
