Barret: How much farther do these stairs go on?
Tifa: Why don't you ask them?
Barret: It's not one of them endless stairways or somethin', d'ya think?
Tifa: Of course not!!
Barret: Right... couldn't be that....Are we there yet?
Tifa: Not yet.

Always makes me laugh, and I always think of it now when going up the stairs in a tall building (I dislike lifts XD).

Seifer: "Great. I've got a chicken wuss and a guy who just reached puberty in my squad."

Zell: "I can imagine Selphie now saying, "Woohoo, we're Flying!" with Irving sitting right next to her." Selphie: "Woohoo, we're flying!"

Genesis: "Hmm... how noisy. Zack, the puppy dog."

Kefka: "You sound like chapters from a self-help booklet!"

Yuna: "Give me a Y!"
Rikku: "Give me an R!"
Paine: "Give me a break!"

Cloud: "No one lives in the slums because they want to. It's like this train. It can only go where the tracks take it."

"You stand before the final dimension, and i am the darkness of eternity." -something like that. infact everything said at the end of the game is pretty good, th one thing that ffix had was excellent quotes.

"To be forgotten is worse than death"

"Why defy your fate? is the will to live that powerful..."

Everything about FFIX was about people living forever through the memories of their loved ones, i like that

"This is not the end. I am eternal... as long as there is life and death"

And finally (lets see if i can remember)
"Peace is but a shadow of death,
Desperate to forget its painful past.
And though we hope for promising years,
And after shedding a thousand tears,
Yesterday's sorrow constantly nears.
And while the moon still shines blue,
By dawn, it will turn to a scarlet hue."

God bless Kuja (...)

Seifer: "Great, I got a chicken-wuss (Zell) in my squad and a guy who's going through puberty (Squall)." (Followed by Zell flippin Seifer off)

Kefka: "Ahem...there's SAND on my boots!"
*guy cleans off boots*
Kefka: "Idiots!"

Celes: "I'm a GENERAL, not some opera floozy!"

Gau: "Is Mr. Thou coming?!"

Kefka: "Welcome to my barbecue!"

Eiko: "My man?! MY man?! Even I've never called him that!"

Vaan: "Uhh, Fran, about that viera saying you said the same thing fifty years ago...how old did you say you were again?
*Fran walks away*
Balthier: "Nice going."
Larsa: "Surprisingly rude."
Penelo: "Try to grow up, please."

Man in Zozo: "Zozo?! Never heard of it."

#@!$*% - Barret/Cid FFVII jus makes me laugh as they dont actually swear

Zack : You are not a monster , those are wings of angels.
Angeal : So tell me! , what do angels dream of !! To become human again ....

Something like that.

Here is another memorable quote from my gal in FFX... This is from the closing part of Yuna's speech during that emotional endscene...

"The friends we have lost, dreams that have faded, never forget them..."
