I don't get why you would facepalm if you're the second main character of the show,
Its the story about Raydog, a normal dog who's memes sucked, but then a normal man named Socrates who lived across the street (While he was rating socks) he heard Raydog raging about his memes, Socrates was so annoyed that he built a raygun, and shot Raydog, and that made his memes great.
