For several years, landlady Edna (Betty Garrett) has been surrogate mother to tenant Laverne (Penny Marshall). Now, it looks like the "surrogate" qualifier will be dropped, as Edna accepts a long-delayed marriage proposal from Laverne's dad Frank (Phil Foster)--who had already reserved the church even before getting Edna's answer. This results in a brief "freak-out" for both Laverne and her roommate Shirley (Cindy Williams), but all ends happily as the girls join an all-black gospel choir in a wedding-day songfest. ~ Hal Erickson, Rovi
