When I was a student, there were of course lots of weird and wonderful and obscure societies. In fact my flatmates and I may have founded a couple.
The reason was simple - if you had an official "society" and got it affiliated to the Student Union, then you were eligible to host an event or two, and student union supplied the meeting room and some beer.
Free beer - the ideal reason to form a society.
This was all just at the tail end of punk, and the punks and anarchists felt a bit left out - everyone else was getting free beer and they weren't.
So they decided to form an "Anarchy Society". Which of course is anachronism, but you can put up with that as long as the beer is free.
However, when the Anarchy Society tried to register itself with the Union, they were told that they needed a written constitution. Which was a problem for anarchists.
So the Anarchy Society simply adopted verbatim the constitution of the Tennis Club, adding a final clause "no member will be bound by any of the above clauses".
