A scientist is conducting an experiment on how far a frog is able to jump. For the first trial he places the frog on the table and says, "Jump frog jump!" The frog jumps four feet and two inches.

The scientist takes out his notebook and writes in it, "With four legs, frog jumps four feet and two inches. The scientist then takes out a knife, cuts off one of the frogs legs and places him back on the table. Again, he says, "Jump frog jump!"

The frog now jumps two feet and one inch. The scientist takes out his notebook and writes down, "With three legs, frog jumps two feet and one inch." The scientist takes out a knife again and cuts off another one of the frogs legs. He places the frog back on the table and yells, "Jump frog jump!"

The frog jumps one foot. The scientist takes out his notebook and writes down, "With two legs, frog jumps one foot." He takes out his knife and again cuts off another leg. He places the frog back on the table and yells, "Jump frog jump!"

The frog jump 5 inches. The scientist takes out his notebook and writes down, "With one leg, frog jumps 5 inches." He takes out his knife and cuts off the last remaining leg of the frog. He places the frog back on the table and yells, "Jump frog jump!"

The frog doesn't move.

"Jump frog jump!!" The scientist yells a bit louder, but the frog still doesn't move.

"JUMP FROG JUMP!" The scientist says screaming at the top of his lungs. The frog still does not move.

The scientist takes out his notebook and writes down, "With all four legs cut off, frog goes deaf."
