Wrong is right, you figure out how

A manipulation is a game in which one or more players are manipulated by the other players into saying or doing something. (I prefer the term manipulation to endowment, because an endowment need not be secret.)

In Improv, everything you say becomes true. Manipulations are a great game for re-enforcing this principle. When the guesser says the “wrong” answer, it is still right. The other players are forced to justify why the “wrong” guess is also true. This should happen in all scenes when your partner says something unexpected or that you think is “wrong”.
