You draw a secret word in a sketchbook and pass it to the next person who tries to guess what you drew. You alternate between drawing and guessing until the book returns to you. It is essentially a visual version of the classic telephone game. It requires absolutely zero artistic skill and bad drawings actually make it funnier. You will end up crying with laughter at how badly the words get misinterpreted. It accommodates large groups easily and works well with almost any crowd you host.
