This is really fun for a big group with imagination! Set up two chairs next to each other and pretend that they are a single park bench in a city park. The idea is to do whatever you can to make the person in the
seat next to you leave the "bench". For example, if you were sitting in one seat and a stranger came up and started hugging you, you would probably leave. When you get the person to leave, you move into their seat
and it's somebody else's turn.
