Who Ya Gonna Call... Beatboxer!

This dude's name is apparently Matt Mulholland and he performs the Ghost Busters theme in 14 part harmony with some old style beatboxin', or maybe it's acappella. Hell I don't know. I do know that I laughed my head off at first, but then it hit me... this guy is awesome. Plus he looks a bit like the Staypuff Marshmellow guy. Bonus!
