Hey, neighbor!

Every once in a while, a noise emanates from my neighbor's apartment that I, through my finely-tuned detective skills, have identified as an Australian aboriginal bullroarer. See video below. It's like that, but about 20 times louder.

Either that, or they're trying to start a propeller plane in their living room.

I wish I had a digeridoo. We could jam.

Now I just feel compelled to find some weird noise so I could compete with them.
