grasshopper

A biology class student conducted an experiment on what would happen to a grasshopper if its legs were taken off.

He pulled off one of its legs and yelled 'hop!', and the grasshhoper hopped. Then he took another leg and yelled 'hop!' and the grasshopper hopped. Then he took all of its legs and yelled 'hop!' but the insect did not hop. He yelled again, but the insect did not hop.

So he came to the conclusion that when all the legs of a grasshopper are removed, it will become deaf.
