Identical Problem/Julie's Old Flame/The Jinx

In "Identical Problem," twins Helen and Ellen (both played by Diana Canova) pretend to be one person, which nearly drives Doc (Bernie Kopell) crazy because Helen is warm, Ellen is cold and Doc is feeling amorous.

David Hedison is "Julie's Old Flame," a guy the pretty cruise director (Lauren Tewes) loved until she discovered he was married.

Ray Bolger and Harriet Nelson are Horace and Henrietta MacDonald, an elderly couple celebrating an anniversary aboard the Pacific Princess in "The Jinx." When Horace reveals that the ship on which they were wed sunk right after the ceremony, the Princess crew is amused.
