During a sabbatical from school, Dorothy (Bea Arthur) seeks out a part-time job. Blanche (Rue McClanahan) persuades the museum where she works to take on Dorothy temporarily -- only to regret her generosity when Dorothy, and not Blanche, is assigned to organize an important banquet. Meanwhile, Rose (Betty White) picks up a stray dog at the supermarket, leading to a variety of negative reactions from her housemates -- and an effort to spike the mutt's water dish with sherry. ~ All Movie Guide
