I saw something very similar to this happen once. Not to a polar bear, of course. But to a
person. And (I'm ashamed to say this) I couldn't help but laugh. What I saw was not quite as destructive as what's shown in this one-minute video uploaded by hoopy316
on May 13, 2007. But it was pretty darned close:
Anyone out there had this happen to you? Or, have you seen a polar bear on a treadmill? Either way, let me know!
