What comes next?

About this activity: Our students like this impro game a lot! A person is on stage and asks the audience "What comes next?" They tell him what to do (e.g. that the phone rings and that he picks it up) and by asking "What comes next?" over and over an ongoing story is told. It usually doesn't take too long until a second or third person enters the stage (for example the boyfriend or a doctor)... Our students tend to be very creative and the stories they invent are often unforgettable!
