Martin Riggs: You want me to drive?
Roger Murtaugh: No, you're supposed to be suicidal, remember? I'LL drive.
Martin Riggs: Anybody who drives around in this town IS suicidal.
Roger Murtaugh: See how easy that was? Boom, still alive. Now we question him. You know why we question him? Because I got him in the leg. I didn't shoot him full of holes or try to jump off a building with him.
Martin Riggs: Hey, that's no fair. The building guy lived.
Martin Riggs: Now we both know why I was transferred. Everybody thinks I'm suicidal, in which case, I'm fucked and nobody wants to work with me; or they think I'm faking to draw a psycho pension, in which case I'm fucked and nobody wants to work with me. Basically, I'm fucked.
Roger Murtaugh: God hates me. That's what it is.
Martin Riggs: Hate Him back. Works for me.
Martin Riggs: Hey, you know what?
Roger Murtaugh: What?
Martin Riggs: Well, I think your daughter kinda likes me.
Roger Murtaugh: If you touch her, I'll kill you.
Martin Riggs: Ha! You'll try.
Roger Murtaugh: Have you ever met anybody you didn't kill?
Martin Riggs: Well, I haven't killed you yet.
Martin Riggs: I don't make things difficult. That's the way they get, all by themselves.
Roger Murtaugh: I'm too old for this shit!
