Plot summary
Fran and Maxwell are thrilled to tell the family that he finally told her that he loves her, and this time he didn't take it back! Everybody is happy for her (except for C.C.) and congratulates Fran. Maxwell reveals to Niles that he bought an engagement ring and is going to propose to Fran that night. He, of course, can't keep a secret and tells Fran, who tells Sylvia, in a chain reaction that results in virtually everybody knowing about it. Maxwell asks Fran to invite her family over, because they're having a very important dinner at the Rainbow Room, and everyone should be there.
All the Sheffield and Fine families gather and wait for Maxwell, who never arrives because he is mugged outside the theater. Afraid something happened, because he wouldn't just leave her waiting, Fran searches and finds Mr. Sheffield unconscious behind the theater knocked out by the thieves who stole his watch, his wedding ring and Fran's engagement ring. Nevertheless, he proposes to Fran.
