The couch is seen inside a human egg cell, which is about to go through the process of embryogenesis. Each family member is a sperm, where they are swimming towards the egg cell and then sit on the couch, thus making the egg cell fertilized. The fertilized egg cell then starts to divide so rapidly that they develop into a Mr. Burns embryo. The Mr. Burns embryo says, "Excellent!" as he puts his fingertips together.
