Every two hours, from 3 p.m. to 5 a.m. ET, Animal Planet taps into Super Bowl fever with its cute and fuzzy counter-programming stunt, Puppy Bowl, which has been around long enough to earn, this year, an “X marks the spot” suffix. It’s puppies rolling around, and doing other cute stuff, on a miniature football field, with kitty capers at halftime and penguin cheerleaders (no kidding) around for this year’s ride. In other words, it’s YouTube without the Internet. Als
