Back at the Barnyard - Season 1 Episode 8

The animals are unable to have Saturday night parties because of the farmer constantly weeping about his lost wife. Otis finds him the perfect girlfriend to make him feel better, but they then realize that she is trying to get rid of the farm animals by kicking them out of the barn and take it over (forcing the animals to stay in the hen house which explodes because of the max capacity of the animals in there). So they dress Pig as rich man to lure the woman away from the barnyard, but Pig wouldn't lie and he confessed to her, which makes the woman leave the farmer. In the end, the animals get to have their Saturday night parties, Pig is heartbroken (which he stops after a few minutes), and the farmer went on a cruise with some ladies.
