Jerk in a Box is 99$cents application from the App Store with little phrases and saying that you probably want to tell your boss, but would never say it. It’s crude, immature, and bane but yet funny and probably a good anger management tool if you go back to your office, shut the door, and start pressing some buttons to vent that anger.

The application says things like “Bite me,” “Please, you’re wasting everyone’s time,” and “You weak, pathetic fool.” This probably makes the iPhone more useful in traffic to control your road rage, especially if you aren’t the audiobook listening type.
