Christopher J. Hanke is making backstage mischief with a tiny sound-effects machine in the latest episode of Frump Tower: Behind the Scenes at “How to Succeed” with Christopher J. Hanke (and Bud Frump). Our fun-loving video blogger challenges his How to Succeed in Business Without Really Trying co-stars, including Rose Hemingway (Rosemary), to react instantly to canned laughter, fake gunshots, “boing” sounds and more. Hanke also provides a handy primer on incoming How to Succeed star Nick Jonas and his brothers and lets us tag along to a voice lesson with renowned teacher Joan Lader. It’s an action-packed video, so click below and enjoy!
