Telephone Game Rules:
Have every person sit in a circle on the ground. Possess the birthday child start the overall game by thinking up a crazy line, for example “Purple cows sit inside the pasture eating grass and making grape-flavored milk.”
The individual should then whisper this line in the ear of the player sitting to her or his left, and so forth around the circle until each one has heard the phrase.
The last participant to listen to the phrase should tell everybody what they believe they heard, and then the birthday child must tell everyone the initial phrase. The whole group will get a great laugh from the silly transformation.
