This is a great one. At Stef's birthday party, we played picture telephone. Everyone has a piece of paper for everyone in the room. On the top your paper pile, you write a phrase. Pass your papers to the next person, and they draw a picture of that on a new piece. Pass that picture to the next person, and they write a phrase of what they see from the picture. This continues down the line until it get's back to you and you read the whole thing to the group.
This telephone message started as "Chet and John are lame." Through misunderstandings, horrible drawings, and Chet's pervert mind, he came up with this: "If you take off your pants for the right person and many people know you, you will get an A+." So we kept it.
