I Like to Graph It, Graph It

You may have done The Worm, The Robot, and maybe even The Macarena, but have you ever done The Graph?  Kudos to Mister x² + y² for thinking outside the box.  He's the only identified dancer who isn't a function.  (x² + y² = constant is a circle.)  While he's not mathematically significant, Mister Crap gets a point for flexibility and reach.
