Growing up a wholesome-looking mid-American beauty, Mary Beth McDonough was perfect to play one of the sympathetic siblings of America's favorite family of the '30s 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. Mary Beth's portrayal of "Erin", the angst-filled yet angelic middle child, was an integral part of the show's success and resulted in the spinoff TV specials A Wedding on Walton's Mountain (1982) and Mother's Day on Waltons Mountain (1982), which 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 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 pattootie she's always been.
