Baseball King Balls Throw the Curveball for You

I wasn't blessed with a modicum of sports talent, but I can get behind this idea: cheating.

Baseball King Balls are specially designed polyethylene baseballs from Japan. By making adjustments to that band in the center of each ball, you can alter their aerodynamics, thereby throwing a sinker, curveball, knuckleball, riser, or screwball at will (no special training required!). The catch? There is no catch! Well...other than the obvious fact that these puppies aren't regulation.

But I'm sure that millions of fans and countless MLB officials won't even notice you holding the Baseball King on the cover of Sports Illustrated. [Japan Trend Shop via OhGizmo!]
