The jokesters are at it again, but this time they’re pulling out all the stops. truTV’s Impractical Jokers is celebrating its 100th episode with the guys' most challenging dare yet: a five story high-wire walk above New York City. Joe, Sal, Q and Murr will all take their turn at walking the wire. Who will walk the furthest distance? Only time will tell.

The jokers are competing for donations to their favorite charities, where the contribution will be based on how far each joker is able to walk. The Impractical Jokers Live Punishment Special airs live on truTV Thursday, September 3, at 10 p.m. ET.

Not only will fans be able to watch the jokers attempt this daring feat, but they are invited to participate by predicting who will make it furthest across the wire. Fans can tweet their predictions using the hashtag #LivePunishment and the hashtag of the joker they’re betting on (#TeamMurr, #TeamJoe, #TeamQ or #TeamSal). A poll will be featured during the live broadcast and will tabulate the Twitter votes in real-time.  Fans can also tune in for a pre- and post-episode digital show, which will feature exclusive video, guests, interviews and a few surprises.

If you’re in New York City during the event, come down to the South Street Seaport for the live event. There will also be an exhibit, The Impractical Jokers Museum of Impractical History, which will feature fan generated artwork and artifacts from the series.

To prepare for the live event, truTV is offering fans a chance to take a look behind-the-scenes of the series with Jokers Week including specials Monday, August 31, through Wednesday, September 2, and a full-day marathon of Impractical Jokers episodes Thursday, September 3, leading up to the high-wire special. 

Additionally, truTV is offering their audience the ability to watch every single episode of the Impractical Jokers – seasons 1 through 3 – on demand. In an unprecedented move, the network will make every regular-season episode to date, as well as Impractical Jokers specials, available via VOD and digital on-demand so truTV subscribers can binge watch whenever and wherever they want via http://www.trutv.com/watch and the Watch truTV mobile app
