It’s Labor Day, which means millions of students will be returning to school this week to try to remember the rote knowledge they’re sure to forget by next summer. Luckily for them, John Oliver took a brief break from Last Week Tonight’s current hiatus to share his own back-to-school crib notes, covering key topics like math, geography and presidential penis nicknames.
