Barbara Bush, the First Lady of the United States from 1989 to 1993, didn't think much of The Simpsons, and said so publicly. Marge Simpson took offense and wrote a polite but firm letter objecting to Bush's characterization of the show as "the stupidest thing I've ever seen." The First Lady responded to Mrs. Simpson's note and apologized for the remark.
