There once was a scientist who was testing a frog. He said, "jump frog," and the frog jumped 8 feet. He pulled out his handy scientific notebook and wrote "Frog, four legs, jumps 8 feet."
The scientist then cut off one of the frog’s legs. "Jump frog," he said, and the frog jumped 6 feet. He wrote in his book "Frog, cut off one leg, jumps 6 feet."
He then proceeded to cut off another leg. "Jump frog." He measured and wrote in his book "Frog, cut off two legs, jumps 3 feet."
He then cut off another leg. Again he said "jump frog," and the frog jumped one foot. He wrote, "frog, three legs cut off, jumps 1 foot."
Finally, he cut off the last leg. "Jump frog." No response. "Jump Frog!" No movement. So he pulled out his notebook at wrote, "cut off all four legs, frog goes deaf."
Which brings us to this story: Drive your SUV, fish goes deaf.
