Well, what do we talk about first in our attempts to answer this question?
a) The defecation habits of non-domesticated mammals of the genus "Ursidae" in sylvan locations?
b) The use of the observable characteristics, such as means of terrestrial & aquatic locomotion and vocal sounds of certain widespread waterfowl in determining its genus?
Now that I have concluded my feeble attempts to dazzle the "hoi poloi", the "unwashed masses" with my pseudo-scientific jargon, here are my answers to the question.
a) Does a wild bear s*&# in the woods?
b) If is walks like a duck, swims like a duck and quacks like a duck then it is probably a duck.
c) or, in the words of the Man who really does know, "By their fruits shall you know them."
Comments BUMP! Thanks for posting Ernest.
