Jim,
 
Is this the best the poor critters can do to defend themselves?  It is my
opinion that the Weasel Wardance is all the proof anyone should ever need
that there could not possibly be such a thing as evolution through natural
selection.  If you were Mother Nature, would you select for hopping
backwards until a creature backs itself into a barrier or falls off a cliff?
Not likely.  Ferrets were created because God has a very big sense of humor
and he could foresee that humans would need all the help they could get
maintaining theirs.  It is the Weasel They-Need-to-Remember-to-Laugh Dance.
