Pretty much all of the dialogue from Lunar: SSSC, especially Nall's ever-insightful commentary. The different versions have slightly different translations, but all of them are gold. One of the best examples of great localization for JRPGs.

Jessica: Wow, Kyle. I had no idea you were such a talented thespian!
Kyle: Thespian? Aren't I the wrong gender for that, Jess?

Nash: Go with you...? Well, protecting beautiful women and simpletons is the duty of every Guild member. All right. I will travel to the hag's house with you. I just hope you all appreciate my exceedingly kind gesture!
Ramus: Ooohh... I think I have a headache...
Nall: I think Nash IS a headache...

Jessica: Kyle, I've seen you do a lot of stupid things, and I've just seen one more.

Nall: Call the men in white coats, this one's a keeper.

(While sculpting Luna)
Nall: Jessica, you used too much clay. They're not THAT big!
Nall: Kyle... you suck.
