Mr. Burns: I specifically said, no geeks!
Milhouse: But my mom says I'm cool...

Mr. Burns: Now that you've agreed to reap the windfall of my death, I must return to my large, empty mansion to rattle around and await the inevitable ... alone.
Marge: Are you thinking what I'm thinking?
Homer: Yeah. Let's push him down the steps.

Mr. Burns: Careful, Smithers, that sponge has corners you know.
Smithers: I'll go find a spherical one, sir.

Mr. Burns: I suggest you leave immediately.
Homer: Or what? You'll release the dogs, or the bees, or the dogs with bees in their mouths and when they bark they shoot bees at you?

Mr. Burns: Men, there's a little crippled boy sitting in a hospital who wants you to win this game. I know because I crippled him myself to inspire you.
Milhouse: (to his mom and dad) I hope they win, or Mr. Burns said he's coming back.

Compadres, it is imperative that we crush the freedom fighters before the start of the rainy season. And remember, a shiny new donkey for whoever brings me the head of Colonel Montoya. (Smithers whispers to him) And by that, I mean, it's time for the worker of the week award.

Hello...Smithers. You're quite good...at turning me on

</i> Mr. Burns

Lisa: And now you can go back to just being you, instead of a one-dimensional character with a silly catch phrase.

Bart: Ay, caramba!
Marge: (Grumbling) Mmmmmmmm!
Maggie: (pacifier sucking noise)
Ned Flanders: Hidely-ho!
Barney: (Belches)
Nelson: HA, HAAAH!
Mr. Burns: Ex-cellent!
(Long pause, then everyone stares at Lisa)
Lisa: If anyone wants me, I'll be in my room.
Homer: What kind of catch phrase is that?

Smithers: But sure I

Mr. Burns: I said hop in.

Captain McCallister: I'll need three ships and 50 stout men. We'll sail 'round the horn and return with spices and silk the likes of which ye have never seen.
Mr. Burns: We're building a casino!
Captain McCallister: Arrr...can you give me five minutes?

Ned: What do you think, Reverend?
Reverend Lovejoy: Once something has been approved by the government, it's no longer immoral.
Crowd: Yeah!
Mr. Burns: By building a casino, I could tighten my stranglehold on this dismal town!
Crowd: Yeah!

Crowd: Yeah!

Smithers: Even so, sir, we could stand to lay off a few employees.
Mr. Burns: Oh, very well! (Points at the monitors) Lay off him, him, him, him...(Sees Homer wearing Kissinger's glasses) Hmm...better keep the egghead. He just might come in handy.
