Religion is a classroom where the students have to show up every day but there's no teacher.

There are a bunch of books around and no one is even sure which one is the textbook. Some students insist on one book; others argue just as hard for another.


Then suddenly, on the last day, the teacher appears and says he’s been watching everybody the whole time. He praises the ones who chose the right text-book and sends them off to have cookies and milk…. And then sets everyone else on fire.
