Divide the group into 3 smaller groups...Betty, Popeye & Wolf. When you mention "Betty" that group stands up and says: "Boop-Boop-De-Doo" (with hip action). When you mention "Popeye" that group stands up and says: "Well, blow me down" (with arm waving action). When you mention "Wolf" that group stands up and gives a "Wolf Whistle".
Here's the story to read:
"Once upon a time, there was a charming young lady named BETTY (pause for group action each time you mention Betty, Popeye & Wolf) who was loved by a sailor called POPEYE. BETTY lived near a great forest in which there roamed a big WOLF. One day BETTY decided to visit her grandmother who lived in the heart of the forest where the WOLF lived, but BETTY would not listen and would not let POPEYE accompany her. Soon the WOLF followed BETTY, and he crept closer and closer. But, behind him came POPEYE! Just as the WOLF was about to leap on BETTY, POPEYE killed him with his trusty club and saved BETTY'S life. Thus the end of the story of POPEYE, BETTY BOOP and the Big Bad WOLF.
