TRUTH AND LIES
The class divides into pairs. In each pair, one is the questioner and the other the answerer. The questioner asks questions in rapid succession. The answerer myst answer the questions, alternating between true answers and lies. he must not hesitate or laugh, and he
must keep strictly to the alternation. If the answerer hesitates or laughs, or if he fails to alternate between truth and lies, he is "out" and the partners reverse roles.
