Penn from the team Penn & Teller does a radio show everyday and had on the creators of Southpark recently, Trey Parker & Matt Stone. You can download the whole 45 minute interview here but there is a 5 minute exchange that you need to hear. In it Penn and the guys talk about the loonies we call 9/11 Truthers. Funniest thing is that after Southpark did the 9/11 episode many of the crazies thought it sided with them.
Well, I do believe they were wrong: (h/t Screw Loose Change)

I take it you’ve seen the south park episode? Hilarious! It was conspiracy day on Michael Medved, and he featured some soundclips from the SP ep.
I think it’s pretty obvious that Trey and Matt are not on the side of the Truthers.
Ditto Word! But is anyone surprised that the Truthers would see it that way? After all, these are people who can redefine reality and facts at will.
They’re perfect Democrats.
Notice how often the word “truth” in one form or another gets abused by loonies?
Joe Wilson lied like a rug thoughout “The Politics of Truth.”
Al Gore’s film was called “An Inconvenient Truth.” The film may have been inconvenient, or annoying. But “truth?”
err? hang on a tick…. so you’re telling me that an inconvenient truth is total BS and humans aren’t the leading cause of global destruction?
Wow…! I feel so much better now! Lets all go out for lobotomies and Micky D’s!
I am continually amazed that people will believe anything and everything that’s spoon fed them. They do no research on their own, instead they watch a movie done by a politician with many many mistakes, distortions, and outright lies and think they know the answer. The answer? The eeeeviiiil humans and the corporations.
Go back to your bong, I think the few brain cells left inside your head want to commit suicide.
