You can also get these rings in Bismark or Fargo. They are called, respectively, South or North Decoder Rings.

Never forget That Which Has Been Written By The Elves:

Three Rings for the Joe Clones under the sky,
Seven for the CHFC as they sit stoned,
Nine for Bee-Dubya doomed to clays,
One for King Khandu on his dark throne
In the Land of MOAB where the BS lays.
One Decoder Ring to rule them all, One Decoder Ring to find them,
One Decoder Ring to bring them all and in the darkness bind them
In the Land of MOAB where the BS lays.
Doo dah, doo dah, in the Land of MOAB where the BS lays,
Oh, de doo dah days.
