When the rest of the prospective brides hear about the inheritance, they show up at the ceremony and a free for all ensues. Shemp marries his student before the deadline, and then finds out that there is no inheritance. Moe and Larry have tricked him into marriage as revenge for their marrying his shrewish sisters.
