I am just glad the bear was not harmed.. too often in these stories, the poor animal ends up being shot in order to save the idiot human. I am specifically thinking of those morons at the San Francisco zoo who teased a lion.
Apparently he just took a bite and then spit it out.
He had good taste.
During the early '80's in my home town, a drunk frat boy jumped into the Polar bear enclosure, which looks like it was very much like the one in this story. Those bears were almost killed as well as some people wanted to recover the remains of the kid from the bears digestive tracts. But, common sense prevailed and I believe they were spared.
