A guy in Sequim, Washington had issues with his neighbors because they painted their house bright purple and pink several years ago. So he mowed the word "A-HOLE" into his lawn, with an arrow pointing at the house.
That's good revenge . . . but here's how it gets way better.
He mowed it large enough that Google Earth's mapping satellite caught it . . . so now it's immortalized forever online and it's going viral.
