4x15 - Hercules: The Legendary Journeys

After an earthquake shook Los Angeles, the writers and producers of Hercules discovered their star, Kevin Sorbo, had disappeared. An emergency staff meeting was called in the show's production offices. Many solutions to the problem were suggested and rejected. Unable to find a suitable replacement to play Hercules, the writers and producers got into a brawl. Then Ares and Strife appeared, pleased at the pandemonium their earthquake had caused. Just before the show could be cancelled, Kevin Sorbo showed up, fresh from rescuing people throughout the area. Sorbo was in fact Hercules, just pretending to be a mortal actor.
