Unlimited Improv

It's your first time going to improv, and you misread the flyer. This isn't a class, or even a mundane exercise its... "Unlimited improv" you're not entirely sure what that means, but you can't help but notice the heavy metal door locking behind you as you step behind the stage. You're here until morning, you must do as the audience demands, and if you fail to entertain them you will get the hose.
