I am not going to bother trying to start one.... Mostly because I go to a Christian Private School. More than once has Pastafarianism been mentioned in my World Views (a mix of philosophy, politics, and religion) class. It is usually mentioned in a light-hearted humorous manner, but such a club would not be allowed, joke or not.
That's ok, though, I graduate in 4 months. I will be attending North Carolina State University, and if there is a Pastafarianism club there, I will join it, but if not, I may try to start one.
