Step by Step Season 5 Episode 16

Secret Admirer

Frank buys Carol a fake Swiss Rolet watch (for Valentine's Day) and pretends it is the real thing. Carol feels so bad about Frank spending too much money that she tries to return it, and gets thrown in jail. When Frank bails her out, she tells him that she loved the watch because it was from him, and that the most important thing is honesty. Frank sweeps Carol off her feet with one of Cody's letters, but Carol is even more impressed that he tells the truth about it. Dana gets dumped just before Valentine's Day and turns into the man-hater she can be. Cody writes her ""Secret Admirer"" love letters to help lighten her up, hence improving her personality. It works perfectly and allows Dana to get a boy that she really likes.
