Duncan MacLeod is Immortal, and must live in modern society, concealing his true nature while fighting other Immortals.

Methos: A couple of medieval songwriters come up with the idea of chivalry one rainy day and you embrace it as a lifestyle. You live and die by a code of honor that was *trendy* when you were a kid.
Methos: What do you expect? Einstein? Freud? Buddha? Sorry Joe, I'm just a guy.
Methos: So I'm a little weak on pop culture. Well, who the hell is Chubby Checker in the grand scheme of things, anyway? I mean I, I know how tall Nero was, Caesar's favorite food, I know Helen of Troy didn't have that great a face and it only launched a hundred ships not a thousand, and...
Duncan MacLeod: Blah, blah, blah, blah, blah...
Methos: You think it takes courage to do what we do? Face another immortal with a sword knowing only one of you will live. You try being her. You try living one year knowing that your time is running out. That no matter how much you train, no matter how many tricks you have, you STILL lose. That's the way it is for them. So little time for them to SEE anything or DO anything.
[Referring to Duncan]
Connor MacLeod: He has most of the fun, and all of the good women.
Methos: Just because I don't like to fight, doesn't mean that I *can't*.
[after waking, becoming an Immortal]
Richie Ryan: Mac, I'm alive.
Jack: Last request?
Joe Dawson: Yeah, I'd like to die of old age.
Methos: Grab a beer. There's a cold one in the fridge.
Duncan MacLeod: I know, it's my fridge.
Methos: You know, considering how shot to pieces you were, it's amazing you're still alive.
Joe Dawson: Ow! Considering who's treating me, I'd say it's a miracle. Watch out. Ow! Where'd you say you studied medicine?
Methos: Heidelberg. 1453.
Joe Dawson: Did you major in medicine or dueling?
Methos: Both. A couple more days, you'll be able to travel.
Joe Dawson: You don't have to look quite so happy about it.
Methos: You know that run in you had with the Watchers the other night?
Duncan MacLeod: Yeah?
Methos: Jean Dumar. He was killed the same night. I'm sorry, Joe. I know he's a friend of yours.
Duncan MacLeod: Hey, it was the other Immortal.
Methos: Yeah, well you try telling that to Shapiro 'cause he's convinced it was you. Really, guys, the time's come for you two to start a new life somewhere. Bora Bora is very nice this time of year.
Duncan MacLeod: Yeah, well send me a postcard. I'm not leaving.
Methos: Does the term "self-preservation" mean anything to you, MacLeod? Look, you are under a death sentence!
Duncan MacLeod: Yeah, and I will be until they figure out I'm not the killer. Where's Shapiro?
Methos: Right at the moment, busy trying to kill you.
Duncan MacLeod: Where is Shapiro?
Joe Dawson: Look, don't make it easy for him, Mac.
Duncan MacLeod: Look, I'm making it easy for him because that's where the killer would go. Now where is he?
Methos: They're hiding out in a mortuary on the left bank.
Joe Dawson: He is Duncan MacLeod, the Highlander. Born in 1592 in the Highlands of Scotland and he is still alive. He is immortal. For 400 years he's been a warrior, a lover, a wanderer, constantly facing other immortals in a combat to the death. The winner takes his enemy's head and with it his power. I am a Watcher, part of a secret society of men and women who observe and record, but never interfere. We know the truth about immortals. In the end, there can be only one. May it be Duncan MacLeod, the Highlander.
[Opening narration]
Narrator: He is immortal. Born in the Highlands of Scotland 400 years ago. He is not alone. There are others like him, some good, some evil. For centuries he has battled the forces of darkness, with holy ground his only refuge. He cannot die, unless you take his head, and with it his power. In the end there can be only one. He is Duncan MacLeod, the Highlander.
Byron: Do you want a tombstone that says, "He Lived For Centuries" or do you want one that says, "For Centuries He Was Alive"?
Methos: You're not listening to me. I don't want a tombstone.
Duncan MacLeod: He's using your name.
Methos: Well, it's not like it's got a patent or anything...
Duncan MacLeod: You really thought I'd lose?
Methos: Yeah. And you didn't?
Duncan MacLeod: It wasn't about that. You guys still don't get it, do you?
Methos: No.
Duncan MacLeod: I had to take responsibility for what I'd done. Nothing you two could do was ever going to solve it for me. I had to face him and fight the best fight of my life knowing he'd do the same. It's just the Fates that decide the winner.
Methos: Trial by combat. Whoever survives is proved right in the eyes of the law.
Duncan MacLeod: Bright boy.
Amanda: But what if he comes after you again?
Duncan MacLeod: He won't.
Amanda: How do you know that?
Duncan MacLeod: Because I wouldn't.
Amanda: Well, he's not you.
Duncan MacLeod: He's not that different. None of us are. We all make mistakes.
Methos: And we all have mistakes to forgive.
Amanda: Speaking of mistakes, there seems to be an inspector who is determined to put my cute little butt in jail.
Duncan MacLeod: Sorry about that.
Amanda: She won't forgive me?
Duncan MacLeod: Oh no, I don't think she should.
Methos: I think this is my cue to leave.
Amanda: Bye Methos.
Duncan MacLeod: Bye Methos.
Methos: You guys be good.
Duncan MacLeod: If not, we'll try to be better.
Richie Ryan: Come on, do it. Come on, come on, go ahead, do it. When the Quickening knocks you on your skinny little ass, MacLeod's gonna be right there to help you up. I die, you go right behind me.
Xavier St.Cloud: Just how old are you? Are you a Christian, or do you paint yourself blue and bay at the moon?
Gregor Powers: Tell me, how do you handle knowing that one day he's gonna watch you grow old, wrinkle and then die, and eventually move on to somebody else?
Tessa Noel: Were you born sensitive or did you have to study?
[to Duncan MacLeod]
Methos: Don't go, MacLeod. It's a trap, MacLeod. MacLeod, your pants are on fire.
Methos: Talk about the blind leading the visually challenged.
Alexa: Why do you want to go out with me?
Methos: Because the alternative is unthinkable.
[Referring to mortals]
Methos: THey have so little time to SEE anything or DO anything.
Methos: To... dinner, a film, a concert, a smile, a sunset, a walk, all of the above... whatever you would like.
[to Duncan MacLeod]
Methos: Great, you knock me on my bum because I make a bad joke, very macho.
[From "The Modern Prometheus"]
Byron: My task is done. My song has ceased. My theme has died into an echo... It is fit.
Duncan MacLeod: There's a guy watching you, you know.
Amanda: There usually is.
Richie Ryan: Okay, everybody who's an Immortal, raise their hand.
Graham Ashe: We fight to stay alive. Don't forget to live.
Joe Dawson: Sometimes in life you have to do more than just watch.
Carylon: Then who do we get to wear the kilt?
Duncan MacLeod: Mel Gibson.
Richie Ryan: Smooth. Very, very smooth. I'm takin' notes.
Methos: Hitler killed, and Ingrid judged. Breslaw killed, and Ingrid judged. Ingrid killed, and you judged.
Duncan MacLeod: So who's left to judge me?
Amanda: What if I kiss it and make it better?
Duncan MacLeod: How much better?
Amanda: MacLeod, why don't you believe me?
Duncan MacLeod: Experience.
[to Joe Dawson]
Methos: We ate, we drank, we vomited.
Methos: But I want to see *me* live happily ever after even more.
Richie Ryan: Old Timer. Do you have any words of wisdom?
Methos: Nope.
Amanda: The longer I live the more I get attached to myself.
Methos: I was born before the age of chivalry.
Kenny: In the end there can be only one, and it might as well be me.
Sgt. Powell: He says he heard a strange noise, we went to go check it out, and he saw three grown men with drawn swords, having it out.
Duncan MacLeod: Did he also see a guy in a bat costume and a long cape?
Richie Ryan: You know, sometimes you knowing everything gets to be a real pain in the ass.
[muttering to himself after being tossed over a stone wall by Duncan]
Methos: I'm too old for this.
[From "Revelations 6: 8"]
Kronos: You don't understand, I am the end of time.
Duncan MacLeod: You're history.
Amanda: You won't let me change, you know that? You really expect me to steal.
Duncan MacLeod: I expect sharks to bite too. Don't take it personally.
[to Duncan]
Richie Ryan: You know, I used to stay up at night wondering. Thinking that there must be some special thing I'm supposed to do with my life because I'm Immortal. And I had this illusion that because you were my teacher, that you would show me what it was. And you did. I got it now. There can be only one.
Methos (from "Til Death"): It's not going to work McLeod. I haven't felt guilt since the eleventh century."
Methos: Like you said, I go with the winner.
Xavier St.Cloud: I don't sleep with virgins, and I don't kill children.
Kronos: How do you feel?
Methos: Like I left my heart in San Francisco...
Tessa Noel: [with a welding torch in her hand] I may not be able to kill you, but I'll give you a facial you won't forget.
Amanda: For 300 years you've been telling me to go legit. Now that I'm straight you want me to steal.
[At Methos' apartment. Amanda is banging on the door]
Amanda: Methos. Open the door. I know you're there. Methos! Methos, it's Amanda.
Methos: [opens door] Do you want to knock a bit louder? I don't think they heard you in Philadelphia.
Amanda: I'm sorry. It was an emergency, okay?
Methos: No, it was a good way to get your head cut off is what it was.
Amanda: You're turning into an old grouch, aren't you? Or did I interrupt something important?
Methos: Amanda, it is the middle of the night and I wasn't expecting anyone. Give me a minute. You want some coffee?
Amanda: Yeah.
Kristen: Who the hell are you?
Methos: A man who was born long before the age of chivalry. Now pick it up.
Duncan MacLeod: I've just had a thought.
Methos: Ooooooo.
Lord Byron: Life, my friend, is in the details.
