There's a general prohibition for a Jew to lie, except for specific situations such as Darchei Shalom ("to promote peace".)
"To Tell the Truth" is an old / revived U.S. television game show where 3 contestants appear before a panel. All 3 contestants attempt to claim that they are a specific person. Only one of the three is the actual person and the other two are impostors. (I.e., they lie and try to mislead the panel into thinking that they are the real person.)
Since the rules of the game are known in advance, and the panel expects that two of the people will lie, would a Jew be allowed to be one of the impostors on this show? Or, is this still considered a prohibition of lying?
