Glenn shared heart-warming memories of his grandmother during Glenn Beck Presents: Christmas Cheer! on Saturday evening.
"She was the sweetest," Glenn said. "Unless you wanted her sugar cookie recipe. Then, she'll shiv you!"
Glenn recalled times his sisters would try to get Grandma to tell them her secret sugar cookie recipe, but whenever she wrote it down, there would be some extra ingredient that would ruin the end product.
Finally, Glenn said, one of his sisters got Grandma to make the cookies in front of her so she saw how they were made. Now, Glenn's sisters won't share the recipe with him.
Glenn went on to tell the "true" story of how his grandmother passed away while baking sugar cookies for her grandchildren. Watch.
