Gah, movie characters always know exactly what to say at exactly the right time, don't they? In any given situation they're ready with a witty remark, an off-the-cuff comeback, or a particularly stinging insult. How do they do it?
Well, obviously they have the benefit of Hollywood writers poring over their every word, along with numerous takes and reshoots to really nail that delivery. So really, you shouldn't feel so jealous. It's like they're not real people.
So if you can't beat 'em, join 'em. And by join 'em, we mean steal their insults and pass 'em off as your own. Here's a bunch to get you going - but if you get called up to Movie Court for thieving insults, we ain't going down with you. You're on your own, chump.
