Discovery App Lets Viewers Call Penn & Teller's Bluff

Discovery Channel is launching a live companion app for the Wednesday premiere of Penn & Teller Tell a Lie that will let viewers play along -- and see if they can discover which of their outlandish tales is the tall one.

The show will feature several incredible claims by comedian/magician duo Penn & Teller. The companion apps will let viewers cast votes during the show about which ones are untrue, with results presented live during the premiere.

"If there are two things Penn & Teller stand for, it's the truth and lying, although not necessarily in that order," Penn Jillette said in explaining the premise. "This show has both."

The six-part series is slated to air Wednesdays at 10 p.m. ET/PT beginning Wednesday, Oct. 5. The viewing audience's final results will be revealed at the end of each episode (with different results for Eastern and Pacific airings).

In each episode, Penn & Teller will make several seemingly implausible claims, backed up with scientific information, including that: you can melt steel with bacon; you can lift a car with a head of human hair; and a linen shirt can stop an arrow.

The "Guess the Lie" game is the network's second live co-viewing app, following Discovery's Shark Week Live this summer. The app also will provide users bonus content to complement live tune-in, with video revealing how Penn & Teller were able disguise their lies.

"Guess the Lie" is available as an update to Discovery Channel HD for iPad App, and as a standalone iPhone app. Viewers also can play online at

Penn & Teller Tell a Lie is produced by Discovery Studios for Discovery Channel in association with 1/17 Productions and Creative Differences. The live voting features are provided by LiveHive Systems, which also handled the Shark Week promotion.
