We've all dealt with neighbours that were less than ideal at one point or another. The kind of neighbours that constantly harass you for the smallest thing, the kind that sound like their place also doubles as a bowling alley late at night when you're trying to sleep, or even the kind that tend to, ahem, "express their affection" in a loud way.In this video, we've got a case of a particularly loud neighbour and one guy who has found quite an ingenious way of solving the problem. Instead of wasting his time actually walking over and asking him to turn down his music that constantly blaring, he decided to rig up a little device that responds to any loud noise above a certain limit, hooked up to a couple of massive speakers aimed directly into their shared wall.What does the device do? Well, I guess you'll have to watch the video to find out. Safe to say his neighbours may think again before throwing a party mid-week. Check out the video above to see this guy's epic revenge!
