Gun dealer (on the rifle he has just sold to Kellerman): Serial numbers have been cleaned. Chamber's been scraped to throw off ballistics just in case you're not, you know, shooting at tin cans.
Kellerman (looks up at him): No, I'm hunting bigger game than that. (Kellerman then pulls out his silenced pistol)
Gun dealer: Hey, hey.
(Kellerman quickly shoots him in the chest, then again when he is down on the ground)
