That is funny, Kevin! "Deep six" is a term that I would have thought would span the Atlantic, because I assumed it came from sea chanteys as much as anything! (ala Davey Jones Locker). I assume six fathoms or (as the wiki site said) the depth in feet of the grave. I'm sure I picked it up at home long before the Nixon troubles. I grew up in a major seaport, so that might explain it.
