Impractical Jokers (2011)

Each episode contains a regime of multiple challenges in teams, independently or against specific jokers in a head-to-head challenge. Every time they fail to complete a task, the joker will receive a red thumbs-down. The joker with the most thumbs down after the series of challenges is the loser who must complete an extremely embarrassing or difficult task and cannot refuse to try it. These Loser Challenges have consisted of dangerous stunts and some scary scenes. —Sam Sneddon
