Great punchline to Michael Chabon's story of how he dealt with the n-word while reading "Tom Sawyer" and "Huckleberry Finn" to his children last summer:
"Hey, Dad," the little guy asked me at one point. "How come if you can't say you-know-what, when you were reading Tom Sawyer you kept saying INJUN Joe, because that's offensive, too.""Because I'm an ass," I said. Only I didn't say "ass."
