A scientist has discovered that cockroaches actually hear through their legs and not through their ears like other animals. On the first day of his experiments, he places a cockroach on the bench, says "March!" and the cockroach starts to march across the bench. He did this a number of times until he was satisfied of the results. On the second day of his experiments, the scientist pulled all the legs off the cockroach, placed it on the bench, said "March!" but the cockroach didn't move. Therefore he concluded that cockroaches become deaf after you pull their legs off.
