Is the bear a Catholic?
The answer to this question is currently unknown, however, it is commonly known that most brown bears are Protestant, making it highly unlikely that this bear is a Catholic. Although he does generally keep with the Lenten tradition of fish on Fridays, so maybe he is Catholic.
But the more important question, of course, is given a neutral playing field, i.e. a swimming pool deep enough for a shark to swim yet shallow enough for the bear to stand, who would win in a fight between a bear and a shark?
