How would a jellyfish write a book anyway?

Mr Costello is interviewed on his book, I'm not a has-been, I'm a never-was

Any guesses as to what the book will be about? What will he write about? He's too gutless to bitch about Howard so that won't be in there. Maybe he'll have highlights like "the time I smirked 564 times in a budget speech." Maybe even, "how I sat around with my thumb up my bum for 12 years while a bunch of numpty voters thought I was running the economy." Better yet, "Chapter One: When opportunity knocks I always have my door dead-bolted." Sucked in to idiots who voted him back in, what has he actually done in parliament besides smirk for the cameras? Well done, voters of Higgins, do you think Peter will share his royalties with you? Chumps.
