Current events: There was a case recently in which a music professor served as a judge in a song contest. In the preliminary round, he scored the highest score for a player, and in the quarter-finals, he gave the lowest score. Eventually the player passed the championship title. The reason is that after the preliminary game, the professor discovered that the player was a student of his own “die” (another music professor).
