Oliver the Eighth (1934)

Barbershop owners Stanley and Oliver both answer a personal ad from a rich widow seeking a husband. Oliver hides Stanley's reply and mails just his own. When Oliver receives a proposal of marriage from the widow, he sets off to start a life of wealth and ease. But just then Stanley discovers his unsent letter and demands to be brought along. At the widow's home, they're informed by the creepy butler that his mistress is crazy; having been jilted once by another Oliver, her hobby now is marrying all the Olivers she can find and then slitting their throats. So far, there've been seven Olivers.
