Plus, Robert's chronic inability to propose to girlfriend Amy (Monica Horan) leads her to surmise that he might be gay in "What's With Robert?" Ray and Debra renew their wedding vows after discovering that Ray has accidentally used their wedding tape to record the Super Bowl in "The Tenth Anniversary ." The season ends with another crisis in the relationship between Robert and Amy, as Robert's ex-wife Joanne (Suzie Plakson) pops up out of nowhere in "Robert's Divorce."
