Comic book geeks know that Master Splinter -- the rat who was the sensei of the Teenage Mutant Ninja Turtles -- obtained his skills when he was the pet of a ninja master. He would observe and mimic his master.
Apparently, then, the bear seen in this video was once owned by a master of bojutsu, the art of the wooden staff.
While some have suggested that the footage is fake, the Telegraph has corroborating information about the "Kung Fu Bear": he's at the Asa Zoo in Hiroshima, where zookeepers encouraged his hobby by giving him sticks.
(A nice historical overview of bojutsu and jojutsu is at koryu.com.)
