Book excerpt: Tony Kornheiser is back. Within these pages, the celebrated Washington Post columnist, Pardon the Interruption cohost, and ESPN radio personality relates his experience as an OnStar user, the proud new owner of the Ronco Showtime Rotisserie & BBQ, and a “phone-a-friend” on Who Wants to Be a Millionaire. And in between, he dishes political commentary on Monica and Bill and George W. and Al. New for the paperback edition is Tony’s final Washington Post Style column. So read all about his quest to fit into size 36 Dockers and his struggle to buy holiday gifts. And know that in the process you’re handing this Kornheiser guy way too much dough for these columns.
