There was a progressive scientist who was studying frogs. In his lab he put a frog in front of a line on the floor and got behind and yelled jump from which startled the frog and it jumped 20'. He was so happy and wrote frog with 4 legs jumped 20' in his records. He then cut one leg off the frog, yelled jump frog and it jumps 15' Shit I got some amazing data. frog with 3 legs jumps 15' he wrote in his lab test record. He cut another leg off and like before he yelled and it jumped 10'. He writes frog with 2 legs jumps 10'. He cuts a third leg off and yells and the frog jumps 5'. Still excited he writes from with 1 leg jumps 5'. He cuts off the last leg and puts the frog in front of the line and yells jump frog, nothing happens, yells a second and third time jump frog with the same results of nothing happened. His eyes are wide with excitement grinning from ear to ear he runs to his table and writes in his test record the final result. Frog with no legs becomes deaf.
