Another great scene is when Bud White (Crowe) goes to Lynn's Home and confronts one of her "guests"

Lynn's client: [one of Lynn's clients refuses to leave; Bud White flashes his badge]
Bud White: LAPD, s**tbird. Get the f**k outta here or I'll call your wife to come get you!
Bud White: [the client gathers up his clothes, and walks toward the open front door]
Lynn's client: Officer...
Bud White: Councilman...

Johnny Stompanato: You want an autograph? Write to MGM.
Ed Exley: Since when do two-bit hoods and hookers give out autographs?
Johnny Stompanato: What'd you say to me?
Ed Exley: LAPD. Sit down.
Lana Turner: Who in the hell do you think you are?
Jack Vincennes: Ed...
Ed Exley: Take a walk, honey, before I haul your ass downtown.
Johnny Stompanato: You are making a large mistake.
Lana Turner: Get away from our table!
Ed Exley: Shut up! A hooker cut to look like Lana Turner is still a hooker.
Johnny Stompanato: Hey!
Ed Exley: She just looks like Lana Turner.
Jack Vincennes: She *is* Lana Turner.
Ed Exley: [stunned] What?
Jack Vincennes: She *is* Lana Turner.
[Lana throws a drink in Ed's face]
