Kay: This caused the 1977 New York blackout. A practical joke by the great attractor. He thought it was funny as hell.
[from trailer]
Kay: We are the best kept secret in the galaxy. We monitor, licence and police all alien activity on the Earth. We're your first, last, and only line of defense. We live in secret, we exist in shadow.
Jay: And we dress in black.
Kay: Do you remember the little red button?
Jay: [warily] Yeah...
Kay: Push the little red button.
[Jay pushes it]
Kay: And you may want to put on a seatbelt...
[the car flips upside down, sprouts rocket engines and begins riding along the top of the tunnel. Kay is safe because he has a seatbelt
on, but Jay is flipped over]
Jay: Kay! Kayyyyy!
Kay: [looking skywards] They're beautiful, aren't they?
Jay: What?
Kay: The stars.
Jay: K, you're frightening your partner...
Kay: I haven't been looking for a partner. I've been looking for a replacement.
Jay: K, I can NOT do this by myself, all right?
Dr. Weaver: Hey, guys, can you drop me off home? My apartment isn't in this area...
Kay: I've just been down the gullet of an interstellar cockroach. That's one of a hundred memories I don't want.
Dr. Weaver: What's with the cat?
Cop in Morgue: Oh, the cat. Yeah, well, there's a problem with the cat. Sign here.
Dr. Weaver: [signing] What's the problem with the cat?
Cop in Morgue: It's your problem.
[leaves chortling at his own joke]
Dr. Weaver: I hate the living.
Kay: Arquillian battle rules, kid: first we get an ultimatum, then a warning shot, then we have a galactic standard week to respond.
Jay: A galactic standard week? How the hell long is that?
Kay: One hour.
Jay: One hour... then what?
[the message translation flashes across the screen: "MIB, DELIVER THE
GALAXY OR EARTH WILL BE DESTROYED."]
Jay: Oh, now that's bullshit.
[the message adds, "SORRY." The countdown begins]
Kay: Look, kid, to keep the bugs from getting it, the Arquillians WILL destroy that galaxy.
Zed: And whatever planet it's on.
Jay: You're talking about us?
Zed: [chuckles] Sucks, huh?
Jay: Unlimited technology from the whole universe, and we cruise 'round in a Ford P.O.S.
[after Kay informs Zed that they have a bug]
Jay: And what, we don't like bugs?
Kay: Bugs thrive on carnage, Tiger. They consume, infest, destroy, live off the death and destruction of other species.
Jay: You were stung as a child, weren't you?
Kay: Imagine a giant cockroach, with unlimited strength, a
massive inferiority complex, and a real short temper, is tear-assing around Manhattan Island in a brand-new Edgar suit. That sound like fun?
[the Edgar-Bug has just captured the deputy medical examiner Laurel Weaver and is holding her at ray-gunpoint]
Kay: Let her go, shit eater.
Bug: Oh, listen, monkey boy. Compared to you humans, I'm on the top of the evolutionary ladder, so can it, all right?
Kay: You're breaking my heart. Show me your face and I'll cure all
your ills.
Bug: You ever pull the wings off a fly? You care to see the fly get even?
