Laloo is doing dissection of a cockroach. He cuts its 1 leg, and says, "walk", it walks.
He cuts 2nd and 3rd legs and said, "walk", it walks.
He cuts all the legs and said, "walk....", cockroach can not walk.
Finally Laloo wrote the conclusion..
"After all the legs of a cockroach are cut - it can't listen to you, it becomes deaf..."
