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.
