This is the greates show in Japan. Its called Gaki no Tsukai ya arahende (translates to I'm not a kid's servant). Usually they do stupid/silly games like these, but every new years, they have a longer episode, which consists of the main comedians on the show having to survive a day at some institution (ex. schoo, hospital...etc) without laughing, when the writers of the show set up various jokes. If you go to youtube and search Do not laugh you might find a couple of videos. They are hilarious.
