With all of that space travel going on, there's got to be plenty of downtime for the last Spartan in existence. Sure, Master Chief can just hop into a cryo-chamber and saw some wood between Halo games -- but every now and then, when nobody's around, MC likes to exercise the old pipes. You would not believe how dynamic his range is, clearly exhibited in the video past the break from IGN.

Oh, and before you watch the video (and inevitably call that number to order your own set), know that we think we've finally figured out John 117's identity: Michael McDonald.
