Plot summary
Lois' parents Victor ( Robert Loggia ) and Ida ( Cloris Leachman ) visit and don't approve of anyone in the family except Reese. Hal buys a new refrigerator as Victor promised to reimburse him for it, but Victor changes his mind. Victor also gives Reese a case of his old grenades from World War II, but Reese pulls the pin and Victor breaks the handle off, so Malcolm throws it in the new fridge to keep it from destroying the house. Hal gives Victor and Ida an ultimatum: if they do not compensate for the destroyed fridge, he will report them to the police for child endangerment. Meanwhile, Francis is sick from bad sushi while he and the cadets are in New Orleans for Mardi Gras, staying in the hotel room all weekend.
