Lars Monsen and a bear

Lars Monsen, Norway's answer to King of the forest (which really are moose) ... hehe. He walked across Canada in 2007. The trip he spent 2 years and 7 months on. During the trip he met the bear in Canada skaoger.
Why is he screaming in English, people asked him.
Lars Monsen says only
-Because the north american bears can not speak Norwegian well,
DOH!
