Without even getting into the question of whether a bear could be trained to do all of this (no), the video reeks of manipulation simply from a visual standpoint. Unfortunately I'm not equipped with the tech know-how of Captain Disillusion here to break it down for you frame by frame, so I can't prove it beyond, "I can tell it's fake because of the pixels". But I think the trained eye will immediately spot this as a fake.

I appreciate the skeptical thinking, but you also need to ask "would faking the video take even more effort than doing it for real?"

Ah, but you need to go one step further and ask, "why was this video created in the first place?". If this video is authentic and the guy made it to showcase his hoolahooping bear, you can be damned sure he'd be cashing in on it from here to Timbuktu. If you dig a little deeper you can find a series of these videos (all with the tell tale marks of a hoax), but the last time I checked (a few months ago), nothing new was being produced. If it were real, based on the combined views that video has had in countless corners of the internet we'd be seeing this guy and his bear on every talk show and talent show and web channel you could shake a stick at. But nada.

So again, why was this video created? Well, why was the video of the ping pong knives made? What about that one video of the eagle swooping down and snatching up that baby?

Clearly there are people motivated to create such video hoaxes, whether as student projects, viral marketing, or original content. The one thing that bothers me about the bear hoax is that, as far as I know, no one has taken credit for it.
