An old man enters a nomadic school. The teacher thought he would be an inspector from training & Educational Ministry, so let him ask some question from the class to obtain what the average I.Q. is. While he gets the students as witness that he didn’t steal the school’s tent and that was the wind’s fault. Then the old man tells him not to be an inspector but a teacher like him in times past and now came to the nomadic school just freshing his memories.
