Synopsis by Hal Erickson
Patte Finley, who later played Bob Hartley's sister, Ellen, on The Bob Newhart Show, guest stars as Twinks, an all-but-forgotten childhood pal of Mary Richards (Mary Tyler Moore). Though the effervescent, syrupy-sweet Twinks ingratiates herself with the WJM newsroom staff, she quickly proves to be an obnoxious pest. The limit comes when she takes advantage of her past relationship with Mary by dragging her into being maid of honor at Twinks' wedding (Mary's "Little Bo Peep" ensemble is priceless). "A Friend in Deed" originally aired on February 20, 1971.
