Here's how this would work:
1) Turn off the air conditioning at the bar about an hour before hand.
2) Everybody stands no more than six inches from each other (all facing the same way) and does the locomotion in place. (Get it, we don't move!)
3) Whenever someone new wants to join the dance, they try to wedge in between two other dancers, and
4) Every so often, a person says "Honk!" and each person in front of them says "Honk" in turn.
I'm game if you are..
