I got a better idea! 3 players stand side by side, slightly in a semicircle.
The middle one starts to tell a story. Every action, every idea that the outside players find ok, they euphorically say "yeah yeah yeah yeah!" - But if someone is not happy with the way things are going, he shouts "I've got a better idea", goes to the middle and continues telling the story until someone else thinks he "has a better idea".
