Growing up as a wholesome-looking, mid-American beauty, Mary Beth McDonough was perfect for a part in Homecoming: A Christmas Story (1971). The show was so full of homegrown warm and fuzzy appeal that it spawned the long-running TV series The Waltons (1972). Mary Beth's portrayal of Erin, the angst-filled, yet angelic middle child, was an integral part of the show's success, resulting in spinoff TV specials. Those specials -- A Wedding on Walton's Mountain (1982) and Mother's Day on Waltons Mountain (1982) -- compose the majority of Mary's cinematic resumé. In an effort to escape from a mountain of a pristine pigeonhole, Mary made her skinful debut in Mortuary (1983), in which she showed her boobs and butt during some sensual lovemaking. She made it back to skin screen again in One of Those Nights (1998). Getting in touch with her inner repressed wild child, Mary had a little ex sex with a former hubby, who freed McDonough's mammy mounties from the confines of her top. You'll have to calm your own John Boy down after watching her eye-popping perky peaks! Mary Beth continued the Walton legacy in A Walton Easter (1997), proving that she's every bit the cutie patootie she's always been. In her more recent work, Mary has settled for less-skinful fare, like the made-for-TV flick Christmas at Cadillac Jack's (2007) and the Hallmark movie Christmas on Honeysuckle Lane (2018). At least her other work makes us say, "Ho, ho, ho!" We're hoping for Mary's nude return -- Mary Beth takes our breath away!
