Wes and Mr. Peepers attend an exercise class while Marge helps Nancy address wedding invitations. Wes injures himself and Marge goes into labor, so that when the baby arrives, both are in the hospital: Wes in the emergency ward, and Marge in the maternity ward.

Mr. Peepers and Nancy prepare for their wedding; each is anxious to see the other, but both are prohibited by Wes, the Remingtons, and tradition.
