text:  This is Fresh Air. I'm Tanya Mosley, and my guest today is Ian Carmel, stand-up comedian and former co-head writer of The Late Late Show with James Corden. He's written a new book about his life as part of the T-Shirt Swim Club. The criteria for this club? Being a fat person in a skinny world. Growing up in Oregon, Ian describes being a chubby kid in elementary school, weighing 300 pounds by middle school and weighing over 420 pounds by the time he was 30.
