stop our son

Mama Bear said to Papa Bear , "go out there and stop our son!" "What is he doing?" Papa Bear asked, already on the run. "He’s going sledding; it is dangerous!" She said, her hand on her hip. Papa Bear ran out, put on his goggles, and pretended he did trip. He fell on the sled and yelled, “Let’s go Johnny!” and they dashed away. The two of them went up and down the sledding hill most of that Thursday. Mama Bear got on the phone and said to her friend, “Worked like a charm.” She had wanted them out while she baked cookies. What was the harm?
