Watch this huge polar bear make out with his human BFF

It's said that a dog is a man's best friend -- unless you're the 60-year-old Canadian shown in this video, in which case your closest buddy is an 800-pound polar bear. Mark Dumas, of Abbotsford, British Columbia, raised 16-year-old Agee from birth -- and now they're tight enough that the pair can roll around in the grass, nuzzle each other and take a dip in the pool without anyone being eaten. What's most amazing -- beyond Dumas still being alive -- is the ease with which the massive bear heaves himself out of Dumas's pool. it's an incredibly human-like motion for such a fearsome animal.
