If you've ever lived in a flat, apartment or any form of building where you've had neighbours above you, then you're more than likely familiar with a variety of weird and strange sounds that made you ask "what the hell are they doing up there?".
While it might sound like they're moving furniture, loudly doing the deed or something so alien to you that you can't even describe it with words, the chances are you're never going to find out. Or at least you weren't, until the folks at Above Average decided to meet their upstairs neighbours to see what it was they were up to that made so much damn noise.
The answer is yes, they are rolling bowling balls around the place and they do take it in shifts to make weird noise in the middle of the night.
