I have been a fan of Penn and Teller for awhile now, and while not a mega-junkie, have always enjoyed their style of performing. They present their argument with no fear of backlash from the groups getting their bluffs called out. I finished watching the whole season in just about a week I was enjoying it so much.
The bonus features are also good if you are a fan of bloopers and such. The bonus "episode" about the ghost is a great view if you are in the mood to watch a blow up doll on a fishing pole. Good times by all.
The only downside is that it has to run out of episodes. As soon as I finished the last episode, I was wanting more. I guess I'll have to buy season 2 soon.
