[Words Of Wisdom]

Magus (Chrono Trigger):  Sigh... To have gained so much, and then have lost it again...
 
Magus (Chrono Trigger):  Except for you and I, this world is populated by cretins...
 
Magus (Chrono Trigger):  If history is to change, let it change!  If the world is to be destroyed, so be it!  If my fate is to be destroyed... I must simply laugh!!

HK-47 (Knights of the Old Republic):  Translation: 98% probability that members of the miniature organic's tribe are being held by Sand People, master. Doubtless he wishes assistance. [There is also a] 2% probability that the miniature organic is simply looking for trouble and needs to be blasted. That may be wishful thinking on my part, master.
 
HK-47 (Knights of the Old Republic):  Definition: 'Love' is making a shot to the knees of a target 120 kilometers away using an Aratech sniper rifle with a tri-light scope. Statement: This definition, I am told, is subject to interpretation. Obviously, love is a matter of odds. Not many meatbags could make such a shot, and fewer would derive love from it. Yet for me, love is knowing your target, putting them in your targeting reticle, and together, achieving a singular purpose, against statistically long odds.

Jaheira (Baldur's Gate): You are amusing ... in a what the hell is wrong with you kind of way.  
 
Minsc (Baldur's Gate 2): I trust those who prey on children no farther than they can be thrown, even if I manage to throw them pretty far!

Minsc (Baldur's Gate 2): What? Boo is outraged! See his fury! It's small, so look close. Trust me, it's there.

Lilarcor (Baldur's Gate 2): I'm sharp, I can come up with something... OK... find someone who knows what you want to know and threaten to kill them! Yeah! Then kill them! Woo-hoo!
