It's all part of his war on literacy (Sad Pussycat)

"Talking about presidents who smoked. You remember George W. Bush? Remember him? He's saying while he was president he would enjoy the occasional cigar. On a rare occasion, he would have a cigar because he said it helped him think. I want to tell you, occasions don't get more rare than that, ladies and gentlemen." –David Letterman

"Now how about this? Dick Cheney had his fifth heart attack. He's O.K., resting comfortably. And the doctor, after they made the diagnosis, stamped his card and now the sixth one is free." –David Letterman

"Former governor George W. Bush is writing a book. How about that, about his eight years in the White House. It's all part of his war on literacy." –David Letterman
