If you’ve been reading The A.V. Club for a while, you’re probably aware that we have a troubled relationship with spoilers… and with the return of spoiler-prone shows like Game Of Thrones and Mad Men on the horizon, the discussion probably isn’t going to abate any time soon. Or maybe it will now, thanks to this College Humor sketch that lays down some much-needed ground rules for navigating spoilers, with the help of human spoilers Bubbles (Andre Royo), Hiro (Masi Oka), Samuel T. Anders (Michael Trucco), Rita (Julie Benz), and other much-loved/-contested characters. It’s funny, sure, but it’s also pretty sage advice for both would-be spoilers and spoilees. Heed, ye denizens of Internet message boards, and live a happier, spoiler-free life!
