If you've ever lived somewhere with neighbors above you, then you'll be able to relate to this sketch from YouTube channel Above Average. The skit takes a peek at what the heck those noisy a-holes get up to which causes them to be so damn loud.
Turns out that the reason you can hear so many different sounds emanating from their place, from bowling balls to balloons popping or wood being chopped, is that they're "noise artists."
Meaning your ceiling is their canvas and they create noise in their apartment as a form of artistic expression. It's the only logical explanation.
