6x20 - The Love Boat

On this Valentine's Day cruise, a singing valentine ""pussycat"" falls for a stuck-up guy who has just been dumped by his girlfriend; the owner of a secretarial agency plays secretary to a writer taking a working vacation, even though he is far better at romancing her than he is at taking dictation and typing up her notes; a womanizing pro football player falls for a snooty, straight-laced college English professor.
