3 players, several chairs on the stage represent the bench.
1 player sits on the bench, the other two try to persuade Player 1 to leave the bench through playing a scene.
Offers must be accepted.
Example 1: A sits on the bench, B begins the scene and mimes a drowning person.
A remains seated.
This is OK, there is only a moral obligation to save A.
Example 2: A sits on the bench. B arrives with a bulldozer. B demands that A leave the bench because be needs to grade the area..
A must leave, unless A explains that as the the activist of Robin Wood he has chained himself to the bench to protest the destruction of the park.
Then B must give up and C starts a new attempt in a new scene at a new location to dislodge A from the bench and to take over himself.
