Zombie Cliché Lookout:

Quick, what’s the best way to recover after sticking your foot in your mouth? If you said that you should immediately launch serveral passive-aggressive attacks at the person you just insulted, well, you’re probably a hell of a lot of fun at parties. In popular entertainment, the guy who can’t help but say stupid/insensative/sexist stuff is generally either a complete sociopath, or a cretin with a heart of gold. The trouble is you’ll never know which until the final reel. Good luck.
