Dunce Wars

Some of the greatest party games are little more than brainless, violent fun and Dunce Wars, one of the stupidest, is also one of the best.
Simply give everyone at the party a cone shaped dunce's hat with elastic to hold it under the chin and also furnish them with a stick (or rolled up newspaper).
Then get them to try and violently knock their opponents' hats off whilst all the time trying to defend their own. The last dunce standing is declared the winner...and told to stand in the corner.
