That video looked legit to me. I have a neighbor who use to have a pet bear (it recently died), and they are playful animals. My neighbor would wrestle with it all the time. That bear in the video seemed young. My guess is it's about 2 years old. That would makes it basically a "teenage" bear, so it should have some of it's childhood playfulness left in him. Bears are agile creatures anyway. You should watch them hunt for fish in the water.
On a side note, does anybody else think that bear was giving itself a blowjob at the end of the video. It had his head buried between his legs, and he was focused on something.
Yeah somebody found him a NEW stick to play with.
