Zeus and Hera get into a tiff after Zeus forgets their anniversary. This causes Zeus to be angry with Hercules when he gives him their anniversary gift, and makes Hercules think they're disappointed in him. Hercules convinces Phil to let him take on his first hero task: defeating a man-eating mare. Meanwhile, Hades, recognizing the tension, uses this to his advantage, convincing Hera that Zeus left her to cloud-hop with Dionysus and convincing Zeus to stay in the Underworld after he sets out the sofa for him to sleep on (claiming that Hera did this). Hades then calls Hermes to gather an emergency meeting of the gods, saying that Zeus and Hera are splitting, and hence their duties will need to be temporarily given to other deities. Hercules has trouble with his task, as Hades has sent Neurosis (Richard Lewis) to make him nervous. He finds himself in a deadly situation with the mare, and beseeches Zeus for help, at the same time Phil beseeches all gods. They all arrive, and Zeus apologizes for forgetting their anniversary; Hera apologizes for not taking into account the business of Zeus' job. They then deduce that Hades deceived them both, and smite him, also apologizing to Hercules for involving him in their argument.
