Reluctantly attending a broadcaster's convention in Chicago, Mary (Mary Tyler Moore) must also endure the company of "Happy Homemaker" Sue Ann (Betty White). Ever on the lookout for hot male prospects, Sue Ann encourages Mary to kick up her heels for a change. The climax of the story tells the viewer quite a lot about Mary -- and even more about Sue Ann. When originally telecast on November 16, 1974, "What Are Friends For?" caused no end of amusement at the Screen Actors Guild because supporting actors Noble Willingham and David Huddleston were inadvertently billed as each other in the closing credits.
