Hercules and the Phil Factor

Hercules and the Phil Factor is an episode of Hercules: The Animated Series. It aired on October 16, 1998.

Summary
Phil is discouraged after his rival hero trainer Chiron (Kevin Michael Richardson) points out that he's never actually been a hero, and therefore can't train them. With Hercules' help, he tries to become a hero, but has no luck. Going through a mid-life crisis, he quits his job as Hercules' trainer and takes up the family spear selling business, also with bad luck. But when Hercules must save the city of Corinth from a bronze bull called Catoblepas (the same city where Phil is selling), he needs his old trainer's help to defeat it. Phil teaches him hands-on sensory deprivation training – relying on the four senses besides sight – to defeat the bull, as its eyes can knock a person unconscious. With Phil's direction, Hercules drives the bronze bull into a river, and proclaims Phil as a hero, as without him, he could not have won.
