it's common in a lot of JRPG's for NPC's to stand still, or walk around on a fixed rout slowly, when in a town. When you talk to them, they say one line of information, telling you about the city or sometimes giving you helpful information. But Star Ocean: First Departure, has many NPC's who say utterly pointless things, and i found this completely hilarious. the one i remember at the moment is an NPC child called "Pudgy"
Pudgy: i hate my name
thats his only line he will ever say... utterly needless, there is no purpose to pudgy's existance but to tell you that you're not the only one who thinks his name is stupid. (his name might not be pudgy, but it was somethign along those lines)
there are other, funnier lines i am sure, but i can't quite remember them at the moment.
Naturally, there is always the "I should have been the one to fill your dark soul with LIIIIIIIIIIGHT!"
