You'll need some post-it notes (or some paper and sticky tape) and a pen.
Each player writes down the name of a famous person on a post-it note (or piece of paper) and sticks it on the forehead of the player to their left, so that the player themself cannot see the name but everyone else can.
Players take it in turns to ask 'yes' or 'no' questions to the rest of the group in order to figure out who they are. For example, 'am I a man?' or 'am I in the entertainment industry?'. If the answer to their question is 'yes' they get to ask another question, otherwise they must drink and play passes to the next player.
The last player to guess who they are must down their drink.
