April 12 (UPI) -- Dorothy Mengering, the mother of David Letterman who appeared on her son's late-night show, died Tuesday. She was 95.
Stephen Colbert, who took over for Letterman on The Late Show in 2015, tweeted out his condolences on Tuesday: "I'm so sorry to hear of Dorothy Mengering's death, and so grateful that Dave shared her with us."
Mengering was one of the recurring characters who appeared on Letterman's NBC show Late Night and his CBS Late Show. A master piemaker, one of her most popular recurring bits with her son was "Guess Mom's Pies."
She was a Late Show correspondent at three Winter Olympics, including the 1994 Winter Olympics in Lillehammer, Norway. She offered to bring ice skater Nancy Kerrigan hot chocolate and asked Hillary Clinton if the first lady could get the speed limit adjusted in Connecticut.
Mengering published a 1996 cookbook, Home Cookin' With Dave's Mom, which included recipes for Dave's Fried Baloney Sandwich, Jan's Sauerkraut Balls and Gretchen's Salad Dressing --tributes to her son and two daughters.
In an interview with the New York Times in 1996 to promote the cookbook, Mengering spoke about her son's sense of humor — and her own.
"Well, his dad had a good sense of humor, but I think he may get it from my dad," she said. "He drove Mother crazy sometimes, cracking jokes. I guess I'm more like she was. I kind of take things more seriously, although I'm much more laid-back than I used to be. Finally, I've learned it doesn't matter if the chores don't get done. The important things get done eventually."
