Jerry Horne: Sheriff, your 24 hours are up. I demand you to arrest my client or release him.
Sheriff Truman: Ben Horne, you are under arrest for the murder of Laura Palmer.
Ben Horne: Great move, Jer.
The Log Lady: One day my log will have something to say about this.
Dale Cooper: Harry, I'm going to let you in on a little secret. Every day, once a day, give yourself a present. Don't plan it. Don't wait for it. Just let it happen. It could be a new shirt at the men's store, a catnap in your office chair, or two cups of good, hot black coffee.
James Hurley: When did you start smoking?
Donna Hayward: I smoke every once and a while. Helps relieve tension.
James Hurley: When did you get so tense?
Donna Hayward: When I started smoking.
Sheriff Truman: Jelly donuts?
Dale Cooper: Harry, that goes without saying.
Man from Another Place: When you see me again, it won't be me.
Donna Hayward: The police didn't love Laura, nobody loved Laura but us.
DEA Agent Denise: I understand we're both staying at the Great Northern. How's the food up there?
Dale Cooper: Denise, you're in for a big surprise.
Sheriff Truman: So are they.
Big Ed Hurley: It's not the first time, it won't be the last, but I'm in that doghouse again.
Bobby Briggs: I got some good news and some bad news. The bad news is that your father has bought a condo in Flip City, and the good news is that he is about to win the Civil War.
Jerry Horne: I am 100% sure that we're not completely sure.
Man from Another Place: Where we're from, the birds sing a pretty song... and there's always music in the air.
Catherine Packard Martell: Didn't he want to talk to me?
Pete Martell: Yeah, but we told him you were on your world tour, he should contact your press agent.
Dale Cooper: Harry, is that bag smiling?
Hank Jennings: You're his whore, Norma.
Norma Jennings: I'd rather be his whore than your wife.
Dale Cooper: Fellas, coincidence and fate figure largely in our lives.
Dale Cooper: Ask me why I'm whittling.
Sheriff Truman: I give up. Why are you whittling?
Dale Cooper: Because that's what you do in a town where a yellow light still means slow down, not go faster.
Leland Palmer: Through the darkness of future past / The magician longs to see / One chants out between two worlds / Fire walk with me. I'll catch you with my death bag. You may think I've gone insane, but I promise I will kill again.
Major Briggs: Achievement is its own reward, pride obscures it.
The Log Lady: My log saw something that night.
Chosen answer: Laura was killed by her father Leland, whilst he was apparently possessed by the spirit BOB. The exact manner of her murder is not clear, as several injuries found during her autopsy we later discover occurred during a separate incident before her murder. We know that she was beaten and killed in an abandoned train car, and her body was then wrapped in plastic and thrown in the river.
