All players sit in a circle. Everyone holds up their hands and then the leader
commands them to put their left hands down ("Left hands down!) on the
floor/table. Then he/she commands them to place their right hand over the left
hand of the person on their right ("Right hand over!"). This forms an interlock
of you and the people on both sides of you. The leader decides which way he
will start by pointing with his finger, and then pats on the table. One pat
continues in the same direction, two pats reverses. The person that messes up,
drinks and becomes the new leader.
