Synopsis by Hal Erickson
All fired up with civic commitment, Mary (Mary Tyler Moore) and Sue Ann (Betty White) volunteer to be "big sisters" to a streetwise pair of teenaged shoplifters (Mackenzie Phillips and Tamu). The plan is to demonstrate to the younger girls the advantages of honesty and integrity. Alas, Mary's noble intentions once again go a-gley, no little thanks to the impressionable Sue Ann. "Mary's Delinquent" was first telecast on November 1, 1975.
