"Hercules and the Owl of Athena" is an episode of Hercules: The Animated Series.
Ares has a settle to score with Athena after she plays a practical joke by shaving his dogs of war. In return, he sends his sons, Fear and Terror, to kidnap her precious Owl of Wisdom to exact his revenge. Athena entrusts the bird to Hercules, which works out nicely, as it is mid-terms week and the owl gives instant smarts to whoever possesses it. But when Hercules inadvertently loses the bird to Ares' dimwitted sons, he is challenged to a game of wits to win him back, and learns a valuable lesson in learning knowledge for knowledge's sake.
