Lines from Heat:
"You can screw my wife, but you ain't watching my f**ing tv" [paraphrase]
Also when questioning another guy in a police interview, Al asks the man do you know X, the guy replies "Who ? "....
Al says "Who, who, who ? .....What are you ? A fucking owl ?"
Not the best film I have seen, but loved the script.
Also: Joe Pesci in The Good Shepherd:
Joe says to a* hole CIA man: "We Italians have the Church and family, the Irish have their homeland, even the niggers have their music, what do YOU guys have ? "
CIA guy says "We are real Americans, the rest of you are just visitors"
Stomach churning stuff from the CIA as usual !
