Impractical Jokers is a hidden-camera prank show starring Sal Vulcano, James "Murr" Murray, Brian "Q" Quinn, and and Joe Gatto, four lifelong friends who compete to embarass each other. The format consists of a set of challenges that test the friends' improvisational skills and their ability to follow instructions through an earpiece; whoever loses the most is put through a humiliating or terrifying punishment at the end of the episode.
