Jack Hopkins was the football coach of an American college. He was always trying to find a good player but he has never succeeded. But one day he found an excellent football player so he went with the boy to the dean of the college to ask him if he could accept him in the school without an examination. After some persuasion the dean decided to ask the player some questions. He had always answered wrong even in a last simply calculation. Mr. Hopkins saw the dean was exasperated so tried to justify the boy but he demonstrate he couldn’t do the calculation too.
