Human Chair
From Acrobalance
This pose is for a two or more people but can easily scale up to as many people as you've got. See the picture at Flickr for an attempt to break the world record for most people in this pose.
Mounting
To start have everyone stand in a line all facing forward. It is important to stand fairly close together. Either starting at the back of the line and working your way forward, or all at once, sit down. As you sit you'll create a lap for the person in front of you to sit on.
