Dirty Harry1971

[After shooting several of the bank-robbers and stopping their getaway car by shooting the driver, Inspector Callahan approaches the front steps of the bank. The bank robber that Callahan shot first, wounding him and forcing him to drop his shotgun, now makes an effort to retrieve it. He pauses as he sees Callahan approach, aiming his revolver.]

Callahan:
I know what you're thinking: "Did he fire six shots or only five?" Well, to tell you the truth, in all this excitement, I've kinda lost track myself. But being this is a .44 Magnum, the most powerful handgun in the world, and would blow your head clean off, you've got to ask yourself one question: 'Do I feel lucky?' Well, do you, punk?

[The thief gives up trying to retrieve his shotgun; Callahan picks it up and starts to walk away, lowering the hammer.]

Thief:
Hey! [Callahan turns around] I gots to know...

[Callahan recocks and aims his revolver and pulls the trigger, but the gun just clicks on an empty chamber, and he grins, laughs, and walks away.]

Thief:
Son of a b*tch...
