ScientistsSidney, an outstanding scientist in his field, along with his assistant Sophie, caught a large bull frog in a local pond. Sidney started the experiment with the bull frog, and told Sophie her job was to write down the results of the experiment.
Sidney drew a line in the sand, placed the frog on the line, and prodded the frog with a small twig from the rear and shouted, "Jump frog!"
The frog jumped and Sidney measured the distance. "12 feet. Write that down, Sophie." he said.
Next, he brought the frog back to the starting point and removed the frog's right front leg. Again he prodded the frog and shouted, "Jump frog!" The frog jumped 10 feet, and on instruction Sophie wrote it down.
Again the frog was brought back, and the left front leg was removed, and again said, "Jump frog!" It jumped 6 feet and Sophie wrote it down.
Again Sidney tried, this time removing the large right back leg. "Jump frog! Jump frog!" he shouted and prodded the frog. The frog jumped 8 inches. "Write it down, Sophie."
Finally Sidney removed the frog's remaining back left leg, put it down and prodded the frog with the twig, shouting "Jump frog! Jump Frog! JUMP FROG! JUMP, JUMP FROG!"
The frog didn't jump. Sophie looked at Sidney, and said, "So what should I write down?"
Sidney thought a moment, and told Sophie to write, "When you remove all the legs from a frog, it turns deaf."
