Dorothy Mengering was an Indianapolis church secretary who found unexpected fame as a correspondent on her son David Letterman’s late-night television show. The Late Show with David Letterman viewers warmed to Mengering's unassuming style when she served as a correspondent during the Winter Olympics in Lillehammer, Norway (1994), Nagano, Japan (1998) and Salt Lake City, Utah (2002).
She also delivered Top 10 Lists from her Indiana kitchen and challenged Letterman to guess what pies she had baked for Thanksgiving.
