If that clip is indicative of their material, I would consider getting Showtime specifically for that show. I absolutely love stuff like that. Plus, from what I've read about it, it's pretty Libertarian-leaning.
I just checked and you can download them off of isohunt.com. Just type in Penn and Teller Bull**** in the search box.
Holy crap! Now I'm pissed. First the muslim attacking the ice cream cones, rex comes back, and now these waste's of life. I wish I could go to a PETA rally. I'd go out behind the house and kill me a mess of squirrels to throw at them. Load up some water guns with fish oil. Maybe tie a cat to my bumber and ride around the block a few times. Bastards!!
i have seen every episode ever made of penn and teller, unless they slipped a few past me in the last few weeks. i agree with almost 100% of everything they ever said, except the episode that was critical of the traditionl family. if you get showtime with digital cable you can watch on ton of them on demand.
