Neu's Law of Idiotic Analogies

With apologies to Godwin's Law...The first party in an argument to resort to a patently idiotic analogy is considered to have lost the debate, and the discussion is terminated.

(This one isn't as good as my other one, and of course neither approaches the originality and brilliance of Godwin. Still, I have been hearing so many really stupid analogies lately, I felt compelled.)
