"Call me a treasure hunter or I'll rip yer lungs out" -Locke

Haha, is it really that obvious that FFVI is my favorite? I guess I'll include some other FF ones then (some of these I like just because of the translation ).

Kou: "Oh ya. What are we supposed to do to get a ride?? Ask them and say please?(I think I kinda messed up the quotes)
THAT'S DISGUSTING !! TAKE A SHOWER BABY !!!!

Its official, Final Fantasy VI is a GOLDMINE for great quotes, especially ones that not only go beyond the game, but parallel past and present history.

Why do people rebuild things they know are going to be destroyed?
Why do people cling to life when they know they can't live forever?
Think how meaningless each of your lives is!
- Kefka
"Life.. Dreams... Hope... Where'd they come from? ...And where are they headed? These things... I am going to to destroy!"
- Kefka
Terra: Life will go on! There will always be people, and dreams!
Kefka: No! I will hunt them down. I will destroy them all! Destroy! Destroy! Destroy!
Locke: We will not allow you to harm another living thing.
Kefka: Mwe, hee, hee! But what fun is destruction if no "precious" lives are lost!
- Terra, Kefka, and Locke
Why not? I don't have anything to lose but my life. . .and I got that for free!
- Setzer
The Reaper is always a step behind me...
- Shadow
What's the most important thing in life? To be free of obligations! Otherwise you lose the ability to gamble...
- Setzer
Welcome to my barbeque!
- Kefka (when torching Figaro)
I will destroy everything! I will create a monument to non-existence!
- Kefka
My life is a chip in your pile. Ante up!
- Setzer
If something were to happen to me, all the world's women would grieve!
- Edgar
Run, run, or you'll be well done!
- Kefka

I know this is a Final Fantasy topic but I have to say these quotes from "The Bouncer" game cuz I beaten it twice already.
Mugetsu(most favorite character)> "I don't care if I destroy my mind......AS LONG AS I SLAUGHTER ALL OF YOU !!!
Kou(another favorite character)> Even if I had nine lives, those still wouldn't be enough for this mission.
Sion> "They don't pay you enough to die....SO PREPARE TO DIE !!!" Or was it "SO GET OUT OF MY WAY !!"....oh well.THAT'S DISGUSTING !! TAKE A SHOWER BABY !!!!
