Scary Tennis Ball-Bouncing Piano Player Will Frighten (And Fascinate) You

This just may be the oddest thing you see all day.

Check out this, um, person playing piano by bouncing tennis balls off the appropriate keys. It's pretty impressive and sure to make him a hit at cocktail parties, but, yes, like you we're confused why this maestro is wearing a mask out of the 'Saw' franchise.

As if that's not creepy enough, can someone please explain why a ventriloquist dummy is sitting there? Then again, please don't. We don't think we can handle knowing.
