A few faves:
"I tried to help you, you son of a b****! Who ever told you the department of the whole world was some kind of giant boy scout camp?" (Serpico)
"Will you go to lunch? Will you? Will you go to lunch? Will you? Will you? Will you go to lunch?" (Glengarry Glen Ross)
"**** Nostradamus! I'm not talking about Nostradamus or Mother Shipton or Russell Grant or Mystic ******* Meg, I'm talking about the Holy ******* BOOK!" (Naked)
"No I wasn't ******* bored, I'm never bored, that's the trouble with everyone, you're all so ******' bored. You've had nature explained to you and you're bored with it. You've had the living body explained to you and you're bored with it. You've had the universe explained to you and you're bored with it, so now you just want cheap thrills and plenty of them and it doesn't matter how tawdry or vacuous they are so long as it's new, so long as it flashes and ******* bleeps in 40 different colours! Well whatever else you can say about me at least I'm not bored!" ( - Johnny on being asked if he was bored in Manchester. From Naked by Mike Leigh. 1993)
