Sal, Joe, Q and Murr celebrate 100 episodes of Impractical Jokers with a LIVE punishment in the heart of NYC. Hosted by Howie Mandel, the hour-long special opens with pre-taped challenges that involve the guys crossing items off their bucket lists, faking injuries at the grocery store and making their glorious return to the infamous two-way mirror. The episode then shifts to South Street Seaport for a four-way punishment in which each Joker walks a five-story-high tightrope, live.
