This one is very good for festive gatherings with Christmas crackers. You need everyone to be wearing a hat, so either use cracker paper hats, or otherwise give everyone a normal party hat.
The game is based on observation. The objective is NOT to be the last person left with a hat on. At the start announce the simple objective, the only rule is that no one can take their hat off until you have. Let another game or conversation take place, and as time goes by, people will take their attention off you, and even forget the game is happening. Eventually remove your hat and watch as people cotton on. Gradually the hats will come off, amidst sniggers and smirks.
Some unsuspecting person (who's probably busy boring everyone with a hopeless story) will be last to notice, and much to everyone's mirth, this person is the loser. Serve up an appropriate forfeit (see our forfeits page), get the hats back on and give the loser the chance to start the next game.
