Eye of the OWL

One person is selected to go up to the front. Everybody else will just stand up. That one person will examine everybody standing up. Then that person will leave the room, and three people will be selected to change their spots or dress different. Then the one person will come back in and if he/she finds the three people that changed he/she will change spots with some one. If he/she does not find the three he/she will get out of the game.
