Andy Griffith loved tossing insider references to his 1960s show into Matlock, here and there. In The Picture: Part 2 (1992), as he grilled Dick Lerner (John Harkins) about his activities one given day, he trips Lerner up in a fib about driving to a breakfast meeting because his car wouldn't start and he had had his car towed to a service station for repair. The name of the service station that towed Lerner's car and repaired it - Wally's Garage.
