After Marshall was living in California, the rest of his family – his parents and two sisters, including actress-director Penny Marshall – all moved out to California, too. Marshall says that because they all needed jobs, he cast them in "The Odd Couple" when he was working on the show as producer and occasionally director and writer. Penny Marshall played the character of secretary Myrna Turner; his sister Ronny came on once as Myrna and also as the sister of Marshall's character, Werner; and Marshall's mother played a tap dancer in one of the episodes. Penny Marshall and their father became associate producers on "The Odd Couple." "This is when I began to make nepotism an acceptable art form," Marshall writes.
