Mark Dumas, 60, is the only man in the world who can touch a polar bear. This guy has massive "stones".  This guy even takes a dip in his swimming pool with his 16-year-old polar bear Agee.  Mark and wife Dawn, 60, train the  800lb bear - the world's largest land predator - to star in high-budget TV ads.   

Even though I am an "animal" guy, there's no way I would try this at home!
