When Sally tells Officer Don she can't take living with Dick, Harry, and Tommy anymore, he assumes that she wants him to propose. Sally realizes, however, that what she really wants is to start living as an independent woman, and they tearfully break off their engagement. When Dick has a tenant-landlord dispute with the Dubceks, he casts Harry out of the family for consorting with the enemy. The situation escalates to the point where Dick, frozen and filthy, is reduced to squatting in his apartment without benefit of heat or lights. The feud ends when Dick realizes he was so preoccupied that he didn't pay attention to an important milestone in Sally's life -- her all-too-brief engagement. When Alissa, the girl of his dreams, gets detention, Tommy works hard to get punished as well, in the hopes that it will provide him with the perfect opportunity to ask her out.
