By now, most people should know the rules of Puppy Bowl. There are puppies, and they wear colored kerchiefs denoting which “team” they’re on, and there are human referees, and a miniature stadium, and… okay, so I just realized I don’t know any of the rules. But there are cute puppies running around all over the place, so what else do you need? A scorecard, perhaps? Or a scouting report, so you can tell the dogs from… the underdogs?
