The internet is full of crazy a cappella covers, but Mike Tompkins is at the top of the game. He can make his voice do everything, so much so that he even helped The Today Show make a video during their Viral Week. YouTube to network TV, not bad.

His latest vid -- a cover of Rihanna's "Only Girl in the World -- is actually blowing my mind because he makes himself sound like a computer. The days of a cappella being a bunch of dudes in blazers saying "shooby doo wop" at your college orientation are long gone.

Plus, who doesn't want to hear a dreamy dude say he wants to make you feel like the only girl in the world? No one. That's who.
