A group of people and alcohol (preferably shots).
The usual setup, maybe get your group of people in a circle if possible.
Questions is a very simple game to play and isn't too challenging. You start by randomly asking someone a question (do not say their name - just look at them or in their direction).
They will have to respond with a question (only) but their question can be towards you or someone else in the circle. If the person being asked the question hesitates or responds with an answer, then they must that a shot.
Ask a question that is vulgar or unexpected. Its great to shock people while you are playing the game to make them hesitate, use our imagination!
