The first and foremost benefit of being a B.I.S.A. member is having a fish that is smarter than you are. This provides mental stimulation for you for years to come.
Always beware though, that the penalities for leaving B.I.S.A. (should your departure be granted) are very, very severe. I'll have to consult the archives, however, I know that one requirement of leaving was drafting a 450,000 word essay, single spaced, on why you should not be a card carrying member.
EDIT: Theo, if any of our membership had even paid a fraction of their initiation fees or membership dues, we'd have quite a warchest of funds to put down rogue organizations like S.O.B.
Unfortunately, we have no funds; therefore we fully support S.O.B.s
