Group lines up sits down, crosses right leg over left leg, crosses arms in front of the chest, and bows head as if to be asleep.
First-person wakes up, nudges the next person, and says, "Is it time yet?".
Each person asks the next one all the way down the line.
The last person says, "Nope" and goes back to sleep.
As the message goes back to the beginning each one goes back to sleep. Do this 3 or 4 times, but not too fast.
Finally, the last person will say, "Yup" and when the message gets back to the beginning, all uncross their legs and put the left foot over the right.
