Matt Farrell: You just killed a helicopter with a car!
John McClane: I was out of bullets.
Lucy McClane: Daddy, you're out of your mind.
John McClane: What're you talkin' about?
Lucy McClane: You shot yourself!
John McClane: It seemed like a good idea at the time.
John McClane: Mia? Oh yeah, skinny little Asian chick? Like's to kick people? Last time I saw her she was at the bottom of an elevator shaft with an SUV rammed up her ass.
Thomas Gabriel: [Probing a gunshot wound in McClane's shoulder with his gun.] On your tombstone, it should say "Always at the wrong place at the wrong time."
John McClane: How about... [grunts.] Yippee-ki-yay... Motherfucker! [Grabs the gun and fires it through himself and into Gabriel.].
Thomas Gabriel: McClane? I thought I killed you already.
John McClane: I get that sometimes.
Matt Farrell: Did you see that?
John McClane: Yeah, I saw it. I did it.
John McClane: You're gonna tell me what I wanna know, or I'm gonna beat you to death in your own house.
John McClane: You don't like Creedence?
Matt Farrell: This is like having a pine cone shoved in my ass.
