Instructions
Hard boil several eggs before your party. Keep a few eggs available that are not hard boiled. Keep all the eggs refrigerated so that they are all the same temperature when you begin the game.
Place some eggs in a basket. Make sure all the eggs are hard boiled except for one and that there are the same number of eggs as people playing the game.
Pass the basket around the group and have each person take one egg. Once everyone has an egg, instruct everyone to hit themselves on the forehead with their egg on the count of three. When the players smash the eggs on their foreheads, one person will be the loser and end up with egg on her face.
