Thanks to the internet, one lucky "Stranger Things" fan has the senior pictures of a lifetime.Twitter user Postydamaris asked David Harbour, who plays Jim Hopper, how many retweets she would have to get for him to join her as she posed for her senior pictures. Harbour told her it would take 25,000 retweets. And she did it. This week the pair published the photos, which are out of this world in the upside down, and it shows the two of them together wearing her school's sweatshirt.
