truTV's hit series Impractical Jokers centers on four longtime friends – Q, Murr, Joe and Sal – who dare one another to do ridiculous things in public, then capture their extreme dares on hidden camera, complete with the unsuspecting public's amused, confused, or flabbergasted reactions. After completing each dare, the guys are given a thumbs-up or a thumbs-down to determine who succeeded under pressure and who collapsed in defeat.
