the original point and click interface, by Smith & Wesson
The original 'Dirty Harry' movie, about 1973. Bad guy, armed with a Walther P38 holding a little boy as Inspector Callahan aims the Model 29.
"I know what you're thinking, punk. Did I shoot 6 times or only 5? To tell you the truth, in all this excitement I forgot to keep count. So the question you have to ask yourself is 'do I feel lucky'. Well do you, punk?"
But the really funny one was in 'Bronco Billy'. Clint Eastwood and Sandra Locke talking, Eastwood says something about being in prison.
SL: "You were in prison?"
CE: "Yes".
SL: "For what?"
CE: "Nine years".
SL: "Why?"
CE: "Murder".
SL: "Oh my God, what happened?"
CE: "I came home early from work one day and found my wife in bed with my best friend".
SL: "What did you do?"
CE: (very matter of fact tone): "I shot her".
SL: "But what about him?"
CE: (confused tone): "He's my best friend."
Good lines. Great delivery.
