Quote from Dorothy in Mother Load
Dr. Halperin: Actually, he's obsessed with your mother. Dorothy: Are you saying that his desire to be with me is really his desire to be with my mother? Dr. Halperin: Wild, huh? It's all subconscious. Sophia represents Stan's own mother who passed away before the two of them could resolve things. Stan: Doc, this is rougher than the session when I thought I was in love with you. Dr. Halperin: I still have the flowers.
