Described by the Publisher/Designer:

Who wants a new way to have fun with friends and family? Collect your Ha Ha, Ho Ho, Hee Hee cards while challenging your friends and family to laugh at your crazy interpretations of improvisational situations, objects, impressions, jokes, and other zany antics. Thats not all, as Heckle cards have you ask playres to do the craziest things, and Jester cards add unexpected strategy. But be careful, Party Poopers end up wearing the clown nose.
