If possible, get to land before fighting the bear. You will have increased mobility and it will be easier to land a jumping punch to the bear's maw.

Don't despair, though, as WikiHowl was the subject of a discussion on Kerrang! Radio a month or so ago, and will be hitting back with even more chuckleworthy Wikihow fodder in the near future. For those of you who haven't already, bookmark WikiHowl now.
