Jennifer Lawrence gives YouTube pranksters Smosh a taste of their own medicine

Break.com’s “Prank it FWD” series is piling on the celebrities for its fourth season, launching today.

In one of the new installments, actors Jennifer Lawrence, Josh Hutcherson and Liam Hemsworth from the Lionsgate sequel”The Hunger Games: Mockingjay – Part 2″ prank Anthony Padilla and Ian Hecox of Smosh (whose channels, like Break.com, are part of the Defy Media family) with the help of one of the comedy duo’s super fans, who is living with a form of muscular dystrophy. The clip is designed to raise awareness for the Center for Duchenne Muscular Dystrophy at UCLA.

Also debuting today is  “All Dogs Must Go: Epic Pet Adoption,” in which the hardworking owner of a Los Angeles animal struggles through a disastrous pet adoption event, until surprised by a crowd of pre-approved adopters ready to provide homes every one of her forty dogs. The episode is sponsored by Barefoot Wine & Bubbly.

The new season roll-out will continue on Wednesday with the debut of an episode featuring “Today” (NBC) co-host Hoda Kotb, who joins the Clevvr “Entourage For The Day” prank in which they turn a teenager’s musical aspirations into reality.

Launched 18 months ago, the Prank it FWD campaign has generated over 100 million views and performed numerous good deeds in the form of pranks, ranging from a  a cop pulling motorists over and giving them $100 for stopping for a good driving to turning a homeless shelter into a 5-star restaurant. Past celebrity participants have included First Lady Michelle Obama and Glen Davis and DeAndre Jordan of the L.A. Clippers. As with previous seasons, Prank it FWD will donate one dollar for every 1,000 views, and an additional dollar for every social mention tagged #PrankitFWD.

“We kicked off ‘Prank It FWD’ in April 2014 aiming to turn the prank convention on its ear and add value into the world,” said Barry Blumberg, Defy Media’s chief content officer, in a statement. “Since then, a campaign built on promoting change through positive pranks has grown into a global movement, making an impact with viewers  that has far exceeded our expectations and continues to change the lives of deserving recipients in ways we never could have anticipated.”
