What happens when you put Justin Bieber's "Baby" and Slipknot's "Psychosocial" in a blender together? The result is more harmonious than you'd ever have believed.

Don't look for these two acts to share the stage anytime soon! They've got nothing in common, except they're both making unpleasant noises into a microphone. However, it's fascinating to see how well they sync up in this video. By the time Ludacris shows up at the eleventh hour (in the Bieber video) it almost begins to feel like some sort of 'SNL' digital short.
