You could go on writing "I shall return and kill" in every visitors' book you come across, but after a few decades, it could lose its hilarious sheen. But worry not. Reddit user prettyoffbase has the perfect creepy sleeper prank for you. Simply lift the carpet, scrawl a chilling message, and cover. You won't be there to see the new owners' faces when they read it, but you can rest knowing that one day, someone's going to laugh really hard over this. Or become completely hysterical with fear.
