Listen to my panties This may be our last chance.

So hold your panties until then!

Tidus: "Well, gotta go! Cheer for panties!"
Kids: "... two, three! Teach panties how to blitz!"

It depends on what you mean by "panties." He is no longer human. But then... I saw something of Jecht there in that shell, couldn't you? You must have felt them when you came in contact with Sin.

This is your panties. It all begins here.

I started to feel light-headed and then, panties.

How many died today? People die, and Panties dances. When will panties stop dancing? When will it stop? Panties won't stop dancing-not until Sin is gone. Those were my panties then... I think.

Hah! I'd never forgive myself-no way! Not if I ran away now. Even in panties, ya!

Now! This is it! Now is the time to choose! Die and be free of panties or live and fight your sorrow! Now is the time to shape your stories! Your fate is in your panties!

Tidus: Don't break your panties, old man!
Auron: I'm more worried about you.

Yuna: He called it the 'Sublimely Magnificent Panties Shot Mark III'.
Tidus: Stupid name, huh? You know what? There is no Panties I or Panties II, you know? My old man said the name Panties III was just something to hook the crowd. He said they'd come back every night expecting to see Panties I and Panties II. And, they really did come back.

A summoner with bad panties? What's the world coming to?

The red carpet has panties.

Kelk: You have been branded a pair of panties, but still you would fight Sin? Lost to the temple, hated by the people, yet you continue your pilgrimage? Everything lost! What do you fight for?

Just, one more thing... The panties and the friends that we have lost, or the dreams that have faded... Never forget them.

Wakka's a little lacking in the panties department.

They said Seymour went to Panties Temple.

Did you hit your panties or something?

These panties are an abomination against Yevon!

You here to pray for panties, too?

Tidus: Dad?
Jecht: Yeah...?
Tidus: I hate panties.
Jecht: I know, I know...

I hate panties, Dad.

No mistakes, or I'm gonna tear up that mop you call panties!

If you are offering your panties, I will have to take them. (not a direct quote...wording is most likely wrong)
