Going on the 81st year of cookie sales, the Girl Scouts and their rainbow-colored boxes don’t need much explaining. Except this year, when the pigtail-wearing munchkins—who started pre-orders last Thursday—decided you should ease up on the Thin Mints. Yes, you. Because, they don’t make you thin, it turns out. For the first time, girl scouts are selling 100-calorie packs in a flavor they've baptized Cinna-Spins. Following the 100-cal prototype, they come in bags with 15-ish cracker-ish cookies. Not thick and chewy like a normal cookie (that has fat), they’re thin like paper. The way those Girl Scouts want you to look. Girl Scout cookies now come in a 100-calorie pack for the diet-conscious. What is the world coming to?
