A scientist at UBC is studying frogs for his final exam. He has been given one frog, knife, notebook, pencil and ruler and is supposed to come up with a stunning diagnosis.
He places the frog on the floor and says "jump, frog, jump". The frog jumps and the man measures the distance. He writes in his notebook one frog, four legs, 11 inches.
The man then cuts off one of the frogs front legs and says "jump, frog, jump". The frog jumps and the man measures the distance. He writes in his notebook, one frog, three legs, 9 inches.
The man cuts off the other front leg and says "jump, frog, jump". The frog jumps and the man measures. He gets his notebook and writes, one frog, two legs, 5 inches.
The man cuts off a back leg and says "jump, frog, jump" The frog jumps and the man measures and writes, one frog, 1 leg, 2 inches in his notebook.
The man cuts off the last leg and says "jump, frog, jump". The frog doesn't move, it just sits there. The man says "jump, frog, jump" louder, but still the frog sits there. The man yells, "jump, frog, jump" but the frog stays put.
The man gets his notebook and writes, one frog, no legs, loses hearing.
