That "P.S." at the end of the letter showed the late First Lady could take a joke and even hand one back to The Simpsons writers! It's pretty funny that Barbara Bush's compliment came not from watching the show, but from looking at one of the many pieces of memorabilia that were being sold throughout the early 90s. Bush had admitted in her interview with People that she only got a "sample" of the program before she made her comment, so perhaps seeing that wonderful camping scene was enough to convince her that she may have been wrong about America's Fox family. Knowing that only makes the story better, as it was clear Bush felt some guilt in trashing the program and wanted to make things right with the people who worked so hard on the show even though she didn't necessarily enjoy the humor.
