Cato Mencken Fellows Penn Jillette and Teller launch a new hour-long show, “Penn & Teller Tell a Lie,” on the Discovery Channel this Wednesday at 10 p.m. Eastern and Pacific Time. Discovery says:

Penn & Teller bring their unique vision of the world in a new interactive series with a twist. In each episode, Penn & Teller make up to seven outrageous claims. While most of the wildly unbelievable stories are absolutely, positively true - one of them is a BIG FAT LIE. It will be up to viewers to spot the fake and VOTE LIVE  online or with the new GUESS THE LIE app.

They’ll put lots of scientific claims and myths through rigorous testing, continuing their longstanding interest in science, truth, and skepticism.

If you have a DVR, note that Showtime is rebroadcasting an episode of their former series, this one a skeptical look at the environmental movement, at the exact same time: 10:30 p.m. Wednesday.

And if you can’t wait till Wednesday, listen to Cato’s podcast with Penn Jillette recorded a few weeks ago.
