Try Not To Laugh Challenge

Try Not To Laugh Challenge is a series that airs primarily on Smosh Pit. One player sits in the "hot seat" and fills their mouth with water; their objective is to keep it in their mouth for the full time limit of thirty seconds. The remaining players take it in turns to try and make the player in the hot seat laugh; they "win" if they make the player spit out (or swallow) the water within the time limit.
