Prof. Farnsworth: Good news everyone!
Bender: I don't like the sound of this.
Prof. Farnsworth: You're all off to Trisol, a planet with three suns-
Bender: Here it comes-
Prof. Farnsworth: Deep in the heart of the Forbidden Zone!
Bender: Thank you and goodnight.

Leela: Uh, Professor, are we even allowed in the Forbidden Zone?
Prof. Farnsworth: Why, of course! It's just a name, like the Death Zone or the Zone of No Return. All the zones have names like that in the Galaxy of Terror.

Leela: Should we really be celebrating? I mean, what if the second garbage ball returns to Earth like the first one did?
Fry: Who cares? That won't be for hundreds of years.
Farnsworth: Exactly! It's none of our concern.
Fry: That's the 20th century spirit!

Poopenmeyer: Alright, places everyone. Prepare for launch.
Farnsworth: Five, four, three, two, three, four, five, six...
Leela: Just fire the damn thing.

Farnsworth: If my calculations are correct, this garbage ball will knock the other garbage ball directly into the sun.
Wernstrom: And if my calculations are correct, we're all going to die horribly.

Farnsworth: Wait! If we could build an object the exact size, density and consistency of the garbage ball, it might just knock the ball away without smashing it to bits.
Leela: But where can we find a substance the exact density and consistency as garbage?
Farnsworth: Alas, I don't know.
Fry: Uh, what about garbage?

Farnsworth: Wernstrom!
Wernstrom: The very same.

Farnsworth: I'm a dried up husk of a scientist. This is all my fault.
Fry: No, it's my fault too. I'm sure I threw out more than my share of that trash up there. Also, one month my toilet broke and it just went straight in the garbage can.

Farnsworth: Now here's the bomb I've prepared. Once you activate it, you'll have 25 minutes to get away.
Leela: That's all? But-
Farnsworth: Now, now, there'll be plenty of time to discuss your objections when and if you return.

Farnsworth: Now, you'll only have one chance to destroy the ball. After that, it will be so close to Earth that blowing it up would cause garbage to rain over the entire planet, killing billions.
Bender: Oh, boo-hoo!

So that's the situation. Due to the short-sightedness of Old New York, New New York is going to be destroyed by a giant ball of garbage.

Fry: So I guess without jobs, we'll be fugitives forever.
Prof. Farnsworth: Not necessarily. Are you three, by any chance, interested in becoming my new spaceship crew?
Bender: New crew? W-What happened to the old crew?
Prof. Farnsworth: Oh, those poor sons of - but that's not important. The important thing is I need a new crew.

Futurama Quotes

Dear Captain's Diary; I may not have found love on this mission but I did find a cute little companion who excretes starship fuel. And that's just as good.

Amy: Is it possible to get everyone back to normal using four or more bodies?
Professor: I'm not sure. I'm afraid we need to use... math!
