Baldwin has bags under his eyes, his normally enviable hair appears as though it’s been beaten flat with a tire iron, and he has two blood-red spots on the bridge of his nose. His whole body looks like it aches. He is keeping it going by alternating between a bottle of Diet Coke and some grainy concoction from Starbucks served in a bucket. This week he is hosting SNL for a record 17th time, expectations are soaring, and the pressure, like the workload, is telling on him like a terrible secret. It’s only Tuesday.
