DESCRIPTION: (from truTV's press release, September 2013) Imagine Dragons, the alternative rock band that topped the charts this summer with the hit song "Radioactive," are set to make an appearance in a special episode of truTV's hilarious hidden-camera series Impractical Jokers on Oct. 24. Airing Thursdays at 10 p.m. (ET/PT), Impractical Jokers features four longtime friends - Brian "Q" Quinn, James "Murr" Murray, Joe Gatto and Sal Vulcano - who take dares to an outrageous level. Ever since they were teenagers, these four guys have challenged one another to do the most ridiculous public dares imaginable. Now, to find out who's best under pressure, they're competing in unbelievably awkward and outrageous hidden-camera hijinks. And at the end of each episode, the loser must attempt the most mortifying challenge ever, which in the case of the Oct. 24 episode means performing as the opening act at a sold-out Imagine Dragons concert, despite a complete lack of musical ability. Members of Imagine Dragons, who are fans of the show, join the non-losing jokers backstage and get in on the fun. Billboard magazine named Imagine Dragons "The Breakthrough Band of 2013," and Rolling Stone magazine called their single "Radioactive" "the biggest rock hit of the year." Impractical Jokers comes to truTV from NorthSouth Productions (Say Yes to the Dress: Atlanta and Double Divas).
