Pour a lot of shot glasses and place them in the middle of the table. Now everyone puts their head down and on the count of three, everybody raises their head and stares at another person on the table. If you stare at somebody who isn’t looking at you then your safe, however if you are staring at somebody else’s eyes then you must yell “Medusa” and take a shot - the same applies to the other person. Continue this until all the shots in the middle are gone.
