We’ve heard all kinds of viral stories about people quitting their jobs, but we don’t get to hear too many stories about vengeful ex-bosses doing stupid stuff after someone quits. It’s not the world’s most earth-shattering prank, but one man decided to deliver the final pay check of someone who quit his auto shop last November by dumping it on his driveway in the form of 10,000 pennies that appear to be dipped in grease or steering fluid.

When all was said and done, the former boss had dumped 504 lbs of pennies on the driveway, along with a note that just said “F$#! You!” He did technically come through with his employee’s final paycheck, but it will take weeks of labor to get them clean enough to turn into the bank.
