What may be the "most exciting and potentially disastrous events of the year"

I'd give a lot to be able to go to the Machine Project Benefit. To be held at a faux Department of Motor Vehicles, this "evening of unbridled confusion" features "car horn fanfare; competitive sobriety tests; workshops on breaking into and hot-wiring cars, as well as how to escape from a locked trunk; home-made beers brewed by members of the Machine Project community; heavy metal polka; surrealistic eye charts; 'secret pancakes'; a human vending machine which dispenses delicious food prepared by Donna Coppola of Auntie Em’s Kitchen fame."

It sounds as eclectic, interesting, and fun as the Machine Project itself. How well do you special events reflect not just your organization's mission, but also its organizational soul?
