This game has been around forever -- and we like to use it during our discussions on "Why it is important to have a Guru."
Have the children sit in a circle. One child thinks of a word or a sentence and then whispers it in the ear of the child sitting next to him/her. Then that child whispers what they heard into his/her neighbor's ear ... and so on. Then the last child announces what they were told to the entire group.
It never fails that what was originally said gets very distorted as it is passed around. In one of our circle times we started with "Swamiji likes oranges and wears grape-colored Crocs." Within one interpretation it became "Swamiji likes oranges and wears cream-colored Crocs." And then, somewhere in the middle of the circle it got changed to "Swamiji wears orange shoes," which ended up as "I have no idea what she said!"
This is definitely a fun game ...
