In his new book, “I Am America (And So Can You!),” Colbert devotes an appendix to his 2006 speech, along with the “back story.”

Of meeting President Bush, he writes: “Then he extended the hand that signed off on ‘Shock and Awe.’ It was as soft as a mitten made from angel food cake. His eyes were steely, and he had the faraway look of a man who was replaying a video game in his mind.”

Colbert jokes that he wore his White House Correspondents Dinner tuxedo to the 2006 Emmy Awards. “After I lost I had it cremated and scattered over Barry Manilow.”
