Monkey in the Middle

Three players do two scenes.

Player A is called the "Monkey".
He plays a scene with player B.
When the host calls it (calling "Switch" or clapping) the "Monkey" must switch to a different scene with the other player C.

The host can torture the players by increasing the speed of the switches towards the end of the game.

A similar game with one player performing in serveral scenes is Revolving Door.
