I just watched the Religulous documentary directed by Larry Charles (who directed Borat, Seinfeld and Curbb Your Enthusiasm) and starring stand-up comedian Bill Maher (who is in the Comedy Central Top100 best comedy moments, hosted Politically Incorrect and currently hosts HBO's Real Time with Bill Maher).

The documentary bills itself as an "uproarious nonfiction film about the greatest fiction ever told."
In a statement about the film, Maher explained his rationale for making it:
It has been my pleasure over the last decade and a half to make organized religion one of my favorite targets. I often explained to people, "I don't need to make fun of religion, it makes fun of itself." And, then I go ahead and make fun of it too, just for laughs.
