Deaf Studies Puns

Two scientists are studying how far frogs can jump. Their first step was to teach a frog to jump on command. This completed, they yelled jump, and the frog jumped 8 meters. Considering what effect each leg had, they then amputated one leg and yelled jump again. The frog jumped 6 meters. After noting this, they amputated a second leg. After yelling jump, the frog jumps 4 meters. This was such an interesting result that they went on to amputate a third leg. This time, the frog was only able to leap 2 meters. Feeling a breakthrough was coming, they amputated the last leg. Despite yelling jump repeatedly, the frog wouldn't move. Their conclusions were that amputation of more than 3 legs causes deafness in frogs.
