Sitcoms tend to spoon-feed you emotions. Each joke is accompanied by a laugh track. Each heartfelt moment brings a collective "aww" from a prompted in-studio audience. And, the insults? Well, they're marked by a stunned face and perhaps an "oooooooh."
The movie zinger, however, is subtle. It's a nuanced art form of barbed phrases, designed to inflict pain on its recipient. The on-screen comeback can be backhanded and clever. Ahead, the sickest of burns we've ever seen on film.
