Tactics Advance 2 "Vaan: I'd say we didn't do it, but something tells me you and reason aren't on speaking terms."
Final Fantasy V Gilgamesh: "Enough expository banter! Now we fight like men! And ladies! And ladies who dress like men! For Gilgamesh...it is morphing time!”
Final Fantasy VIII Laguna: "I see... I didn't understand a word."
Laguna: "It's like killing two pigs with one stone."
Actually, most things Gilgamesh, Laguna, and (TA2) Vaan said in general
Final Fantasy IX Kuja:"But I hate keeping promises... And I so love deceit."
Final Fantasy XII: Judge Gabranth: "Silence! All was stripped from me! Only hatred for the brother that fled our homeland remains mine! Tell me: why do you forsake that which you must hold most precious?"
^ Last one is a favorite of mine mostly cause Gabranth had perfect delivery with this line. It would not have sounded so good if it was a different actor imo
