Garry Marshall
A cruel but beautiful heiress mocks and cheats a hired carpenter. When she gets amnesia after an accident, he decides to introduce her to regular life by convincing her that they're husband and wife.
Joanna hires country carpenter Dean to build a closet on her yacht. When the two don't see eye-to-eye, Dean is left unpaid while Joanna sets sail. The following day, Joanna is fished out of the sea, after falling overboard, suffering from amnesia. Dean sees a neat way to regain the money she owes him - he tells her she's his wife; that way Dean gets a free housekeeper and mother for his four kids.
