Snake delivers the short line 'If you say so' in a flat, gravelly voice over about two seconds, sounding unconvinced rather than argumentative. The clip feels dry, sarcastic and quietly amused, like a reluctant agreement that leaves the other person to carry the conversation. It comes from Metal Gear Solid 2, where Snake uses the line to brush off a claim without starting a fight.
