Synopsis by Hal Erickson
Not altogether certain that she wants a blast from the past, Mary (Mary Tyler Moore) nonetheless attends her high school reunion. During the festiviites, Mary is reunited with her ubiquitous former beau, Howard Arnell (Richard Schaal), who is all for rekindling the old romantic flames. Meanwhile, Rhoda (Valerie Harper), who didn't attend Mary's high school, but has tagged along just to see if anyone will pretend to "remember" her, has a little adventure of her own. Jack Riley, who later played the contentious Mr. Carlin on The Bob Newhart Show, makes his first Mary Tyler Moore Show appearance as Eldon Golfax. "Didn't You Used to Be...Wait...Don't Tell Me" was originally telecast on October 30, 1971.
