Soos' Grandma is hilarious. His life is my soap opera. I liked two more references. When Soos admitted he didn't know whether to call his "girlfriend" Gif-any or Jiff-any, which is of course the uproar caused on how to pronounce gif.
Also when he read the sentence in the game. "Anything can hadplen" or something like that, which is making fun of how bad translations from Japanese to English can be.
