I found this on Google Video. Penn & Teller run a really good show (I think on Showtime) called “Bullshit” where they take topics and debunk them. They’re great skeptics and the shows are usually pretty entertaining. One of my favorites from the first season is on recycling… I will see if I can find it on one of these video sharing sites.
In the meantime, here is a pretty funny / crazy 8 minute segment on conspiracy theories about 9/11. You gotta see how crazy that one guy is when he gets into his car… I knew he was a kook, but that scene just was out of control.
