Patrick Tufts started it all by posting a bogus newgroup proposal in talk.bizarre:

alt.music.philip-glass.philip-glass.philip-glass.philip-glass

This called for retaliation.

alt.music.john-cage.^^.#.~.sound.like.a.growing.plant.%.!.@

I couldn't leave it alone.

alt.music.schoenberg.acgblfeihkdj.akglbhiefcjd.jdkhieflbgca.djcfeihblgka

and

alt.music.steve.reich.eichr.ichre.chrei.hreic.reich

At this point, things got out of control.

I had to stop.
