[Boo has just laughed, and caused a blackout in Sulley's apartment]
Sulley: What was that? Mike: I have no idea. But it would be really great... if it didn't do it again.

[Randall has accidentally captured Mike instead of Boo]
Randall: [angry] Wazowski! Where is it, you little one-eyed cretin?! Mike: Okay, first of all, it's "creetin". If you're gonna threaten me, do it properly. Second of all, you're nuts if you think kidnapping me is going to help YOU cheat your way to the top! Randall: [chuckles evilly] You still think this is about that stupid scare record?! Mike: Well...I did. Right up until you chuckled like that. And now I'm thinking I should just get out of here.

[Sulley has insisted on walking to work]
Mike: You wanna know why I bought the car, Sulley? Sulley: Not really. Mike: To drive it! You know, like on the street, with the honk-honk and the vroom-vroom, and the no walking involved? Sulley: Wa, wa, wa, wa. Will you give it a rest, butterball? C'mon, you could use the exercise. Mike: I could use the exercise? Look at you! You have your own climate.

[after whacking Sulley with a scream canister] You don't know how long I've wanted to do that, Sullivan!

[during ending credits] [to Boo] Go ahead. Go throw up. [crew starts laughing] What? What did I say? What, what?

Don't you ever run away from me again, young lady!

First of all it's cretin, if you're going to threaten me do it properly!

Hello?

Hey, that's my bed! You're gonna get your germs all over it.

Hey, where're you going? We can talk!

How could I be so stupid? This could destroy the company!

I can still hear her little voice.

I can't believe that we're waltzing up to the factory!

I did until you chuckled like that. Now I think that I'll just be going.

I hope you're happy Sulliven, you've destroyed this company. Monsters Incorporated is dead. Where will everyone get their scream now? The energy crisis will only get worse because of you.
