See silly scenes acted out by people who have no idea what they are acting out.
This is a vindictive version of the game Mimed Grapevine. One person is taken out of the room and told to mime a duck landing on a frozen lake or any other extremely silly thing! Meanwhile, an assistant is telling the remainder of the party guests what they are about to see, and to guess anything else all the while encouraging the person to continue their mime. Let this go one for a while and then on a cue from the leader, everybody yells the answer in unision! It may be appropriate to congratulate the victim with the words. "Well Done ... You certainly have been."
