No one does cocky and blissfully clueless quite like Will Arnett. The actor and comedian perfected that attitude on Arrested Development, BoJack Horseman, and 30 Rock. His distinctive raspy baritone gives equal intensity to the Lego movies and GMC truck commercials. And it all comes together on the wildly popular podcast SmartLess. What began as a passion project with Sean Hayes and Jason Bateman exploded into a phenomenon, with SiriusXM recently snagging the rights in a reported $100 million deal. There, Arnett applies his deadpan sarcasm to chats with Bradley Cooper, Selena Gomez, and President Joe Biden, to name-drop a few. Offstage, the real-life nice guy confesses to a weakness for sweets, acknowledges something sad about rice cakes, and stakes his claim to being an early-stage cold-plunger.

WAKE-UP TIME: Six A.M. I go to bed by 10 P.M. at the latest. I put a real premium on good sleep and try to get a lot of it.
