A sample of HK-47 dialogue (as far as I can remember):
Char - "HK-47, do you know what love is?"
HK47 - "Inquiry: Love? Would you mean the word you meatbag- I mean organics use to refer to the emotion equated with a 'warm fuzzy feeling' and a certain degree of contentment?"
Char - "Er...yes?"
HK47 - "Statement: Ah, love. As an assassination droid, I have no experience with such things. However, I believe I can supply you with an answer to your question. Love...is holding an Aratech D-837 Sniper Blaster Rifle with a Tri-Light Laser scope, lining up your target, and blowing out his kneecaps from 3 kilometers away."
Char - "Ooookaaaayy...."
HK47 - "Extrapolation: Master, you seem to be malfunctioning. Would you like me to perform exploratory surgery to determine the source of your error?" *knife blade extends from manipulator*
