This improv game is in the following improv game categories:
One player starts a scene. As soon as the trainer claps his hands, the player needs to make whatever he was doing more interesting, without advancing. If our player was opening a briefcase at the clap, he needs to make `opening a briefcase` more interesting; he is not allowed to take something out of the briefcase, as that would be advancing; player needs to stick to `opening the briefcase`.
