An theater game played by improv Comedy troupes such as ComedySportz. Also seen on Whose Line Is It Anyway? It's not played very often, because it's very difficult.

Two players take the stage. A suggestion for a last line is given by the audience. One player speaks the last line, then they attempt to play out a meaningful scene from the line, ending when one player enters the room.

Often, players will end up waffling their way through the sketch as they try to figure out how to create causality for their current actions:

Player 1:"No, you can't borrow my car!"
Player 2:"Can I borrow your car?"
Player 1:"Why, my car can go twice as fast!"
Player 2:"I'll never get there in time in my car."
