What is the B.I.M.C.? Take your pick:

The Bavarian Illuminati Motorcycle Club is...

...a group of freethinking, like-minded individuals who love riding
motorcycles.

...a collection of anarchists who use the motorcycle as a symbol
of total individual freedom and who are bent on the complete
deconstruction of all heirarchical and authoritarian organizations.

...a group of sacred technicians of psychosocial engineering who use
the motorcycle as a metaphor for conscious evolution and who are
working to bring about the advent of the New Aeon.

...a cabal of the Illuminati Conspiracy that is using the cover of a
motorcycle club to infiltrate biker-oriented organizations as part of
their plan to dominate the world.

...a gang of Discordian pranksters who are using the vehicle of a
motorcycle club to pose as a cabal of the Illuminati Conspiracy with
the aim of causing confusion and chaos that will help thwart the
Illuminati's plan to dominate the world.

...a special multiphase operation of the Illuminati Conspiracy to
attract freethinkers, anarchists, occultists, Discordians, and others
of that ilk and make them pawns in their plan to dominate the
world and bring about the advent of the New Aeon, or to
Immanentize the Eschaton, whichever comes first.

...a figment of the imagination of a twisted mind with a paranoid
fantasy of playing a monstrous joke on upright, clean-living citizens.
