Dear Peter,

    What ring of truth?  It sounds like a hundred other emails that
people forward, favoring simple-minded ease to the boring truth.
 Nothing wrong with enjoying jokes, but why not call them that?
    While you are loth to do any of the work of verification, others
might be interested.  "Raining cats and dogs" derives from myths of the
animals' influence on and symbolism of various weathers.  The thresh is
to tread or trample; the OED is unsure of the hold . Brewer's thinks
bringing home the bacon ("to bring back the prize; to succeed") might be
a reference to the Dunmow flitch.  I know you'll want to research that
so you can educate your student. A wake uses the sense of watch or
vigil.  A bone house is "a charnel-house; a coffin; the human body."
Dead ringer is an American usage, first citation 1891.  And it doesn't
have anything to do with death or bells.
