The Love Boat 7x12

Julie's blind date turns out to be an overweight, uncouth misfit whose advances drive her crazy, that is, until he rejects her; a woman travelling incognito to avoid testifying at a trial falls in love with a man on board, while when disguised in a wig and a childs' dress she tries to avoid that same man's flirting son; a prize-winning author is blackmailed for love by his secretary, who is travelling with him and his jealous wife.
