The most authoritative source for the origins of "foo", "bar" and "foobar"
is <http://catb.org/jargon/html/F/foo.html>.

  When ‘foo’ is used in connection with ‘bar’ it has generally
  traced to the WWII-era Army slang acronym FUBAR (‘Fucked Up Beyond All
  Repair’ or ‘Fucked Up Beyond All Recognition’), later modified to
  foobar. Early versions of the Jargon File interpreted this change as a
  post-war bowdlerization, but it it now seems more likely that FUBAR was
  itself a derivative of ‘foo’ perhaps influenced by German furchtbar
  (terrible) — ‘foobar’ may actually have been the original form.

Much interesting material follows that.  Really surprising in many cases.

It appears that ESR may have missed one of the jokes. "Many smoke but foo
men chew" isn't nonsense -- it's a pun on Fu Manchu, and chewing tobacco.
I think I've actually seen it written as "Many smoke but few man chew"
which makes the punnish origin clearer.  ESR's version may have been
derived from mine ("few man" -> "foo men"), but I don't have a citation
available for mine; I'm just going from old, foggy memories.
