Old Waiter: [Hearing one side of a phone conversation] Hey Max, who's your favorite uncle? Okay, your second favorite uncle? Okay never mind, just listen...

Lindsey: I was just thinking that if you're still alive when I get back from work tonight... maybe, I don't know, we could go out to dinner or something?

The Boss: [after Slevin has just told him he'll take the job killing the Rabbi's son] I knew you had sense.
Slevin: Sense is something you have when you have a choice.
The Boss: Sometimes. Sometimes it's when you know you don't.

The Boss: Yitzchok the Fairy.
Slevin: Why do they call him "the Fairy"?
The Boss: Because he's a fairy.
Slevin: What, he's got wings, he flies, he sprinkles magic dust all over the place?
The Boss: [annoyed] He's homosexual.

The Rabbi: [whispering to Slevin] Whatever they're paying you...
[smiles slyly]
Slevin: [chuckles slightly] There is no "they... " I did this to you. Me.
The Rabbi: You?
Slevin: Me.
The Boss: Who ARE you?

The Boss: You? You're the triggerman.
Slevin: Me?
The Boss: You.
Slevin: Aren't there professionals? People you can hire to do this sort of thing?
The Boss: [laughing] Of course there are. Yes. But you owe me $96,000. Why should I go out and pay someone else when I've already paid you?

Slevin: [from an alternate scene on the DVD] God! This - this smarts. Remember when people used to say that - smarts? Why don't people use that word anymore? I mean, people use the word "pain" way too loosely. There are so many types of pain. I mean, a smart is a sharp, sharp pain. An ache is a dull pain.
Elvis: Hey man, do you ever shut the fuck up?
Slevin: Oh yeah, man, I can be real quiet. One time I didn't talk for three days. People kept coming up to me askin' me, 'Slevin, why aren't you saying anything?' I wouldn't even answer them. I just didn't have anything to say, you know? I can be real quiet. Real quiet.

Lindsey: We are dealing with a bona fide case of mistaken identity here.
Slevin: Yeah.
Lindsey: Things like that aren't supposed to be real. It's like amnesia.
Lindsey: Not withstanding, here you are and Nick's nowhere to be found, so... I'd say you're fucked.
Slevin: Fucked.
Lindsey: Shouldn't you be a little more worried about all this?
Slevin: I have ataraxia.
Lindsey: Ataraxia?
Slevin: It's a condition characterized by freedom from worry or any other preoccupation, really.

The Rabbi: You're unlucky and nothing more than a frame of reference for the lucky Mr. Fisher. You're unlucky, so that I may know that I am not. Unfortunately, the lucky never realised they are lucky until its too late. Take yourself for instance, yesterday you were better off than you are today but it took today for you to realise it. But, today has arrived and it's too late. You
see?

Nick: [on phone] Slevin, do you know what time it is?
Slevin: Yeah, I'm at the airport. Are you sure you want me to come out?
Nick: Yeah, just think... two weeks in New York and the only Kelly you'll remember is the Kelly who gave you your first hand job on the bus on the way up to summer camp.
Slevin: Kelly
Perkins. She told me that her hands were dry and that she needed...
Nick: She said that to a lot of guys. That's why we called her Jerkins Perkins. Just call me when you land, all right?
