I'm a big Penn & Teller fan. I used to watch their old 90s show. I saw them on Babylon 5. I saw all the episodes of Bullshit!. I'm a really big fan.
... and I hated it. With a passion.
It is the single worst show I've ever seen. It is badly produced, badly directed, and it is, on top of that, simply LAME.
Way to try cashing in on Mythbusters. Do not waste your time watching it.
The show is them telling 7 myths, showing them off. The catch is that 6 are true, and 1 is a lie. That's it. And it is on Discovery (not premium cable), so they have to be politically correct.
