Today at Flavorpill, we watched astronauts fall on the moon. We learned the scientific reason why most leftovers don’t taste as good. We met a hippo named Humphrey who mauled his keeper to death, as well as some other much friendlier exotic animals. We looked at some of LIFE magazine’s self-proclaimed “worst” covers. We wondered what this impressive looking Game of Thrones cake actually tastes like — ditto this Ryan Gosling pancake. We thought this tilt-shift video of Belgium was totally adorable. We wanted to give Jason Segel a hug after a 7-year-old critic declared that his face was the worst part of The Muppets. We were impressed by a portrait of Charles Darwin that’s made up from hundreds of stenciled barrel monkeys. We found this analysis of the name-to-title ratios of various authors fascinating. We were frightened by a few of these extreme cigarette holders from the ’50s. And finally, we were thrilled to be a part of Mental Floss’ roundup of the all-time most popular posts from 21 wonderful websites.
