"The Festival of Bad Ad Hoc Hypotheses (BAH!) is a celebration of well-argued and thoroughly researched but completely incorrect evolutionary theory" — in other words, it's a festival dedicated to the ability to bullshit in a plausibly scientific way. And it sounds fantastic. If you're in Boston October 6th, you should totally go. But you'll need a ticket. They're $5 for MIT students, $10 for non-students.
