In 1990 William Bennett, who at the time was drug czar of the United States, visited a drug treatment centre in Pittsburgh and upon noticing a poster of Bart remarked, "You guys aren't watching "The Simpsons", are you? That's not going to help you any." When a backlash over the comment ensued, Bennett apologized, claiming he "was just kidding" and saying "I'll sit down with the little spike head. We'll straighten this thing out." In a 1991 interview, Bill Cosby described Bart as a bad role model for children, calling him "angry, confused, frustrated." In response, Matt Groening said, "That sums up Bart, all right. Most people are in a struggle to be normal. He thinks normal is very boring, and does things that others just wished they dare do." On January 27, 1992, then-President George H. W. Bush said, "We are going to keep on trying to strengthen the American family, to make American families a lot more like the Waltons and a lot less like the Simpsons." The writers rushed out a tongue-in-cheek reply in the form of a short segment which aired three days later before a rerun of "Stark Raving Dad" in which Bart replied, "Hey, we're just like the Waltons. We're praying for an end to the Depression, too."
