Modern justice no longer functions on eye-for-eye principles, and for good reason. But that doesn't mean we can't avenge an eye by causing the perpetrator a nagging little side problem that they can't figure out. Petty revenge is always an option, and these 23 people took to Ask Reddit and shared the vengeful bit of handiwork they're most proud of. 

With so many selfish drivers, a perfect place to enact some petty revenge is behind the wheel. One man described his daily commute; a straight road with a series of well-timed lights that a motorist traveling at average speeds could drive on for miles without coming to a stop. But just one speeder could mess it all up. That's why this man would bait those speeders into running a quick yellow, only to get them stuck in exit ramp traffic while re-passing in the faster lane. Sometimes going slower is faster. 

Read about that man's commuter scheme and other people who exacted higher stakes petty revenge.
