Do religion parodies count as religion?

Last year I first heard about the Invisible Flying Spaghetti Monster (FSM). It was created as a parody in order to prove a point about teaching creationism is school. However a large number of people, mostly atheists and agnostics 'believe' in the FSM. This people are often refered to as Pastafarians or Spagnostics. Even though this religion was created out of parody, more people are starting claim association and are begining to practice the very loose dogma that was set forth by the creator Bobby Henderson.

So does this constitute a real religion? At the moment people do not worship together in large groups, but there is a diffinitve set of symbols and full blown structure and belief system. Bobby has created a complete 'bible' and a full creationist story. This technically fullfills Greers definition by having a set of symbols that lead to lasting beliefs. Does the knowledge that the beliefs themselves are supposed to be a joke actually make the beliefs any less valid? I don't know but I am curious if the FSM is still aorund in 50 years. I wouldn't really be surprized if it doesn't.

Here is a video or two explaining how and why the FSM was created.
