Extremely high-functioning human solves Rubik's Cube while juggling.
He's a witch!
They say we only use like ten percent of our brains (four percent if you've ever left a comment on YouTube). Sir Ravi The Juggler is clearly up to fifteen or sixteen percent at least, so he needs to be apprehended by the CIA and taken in for study and possible lobotomization. He could just be a robot who escaped from his creator or an alien in a skin-suit, but if he's human, he's too powerful. If he ever gets bored with mastering '80s fads and realizes exactly what he's capable of, we'll all be enslaved within weeks.
