Someone's Quote : "I also want to come clean and say it. I never watched the Game of Thrones, not a single episode. I just know that winter is involved (learned this from Twitter memes), and there is a red wedding where a lot of people died (learned this from this CS paper)."
ROFL. And people ask me how do I know about so many films? It's a lot from meme. As those meme become popular when the films are popular. And as time passes, decades pass and over age you see a lot of things and remember a lot.
That's how. Nothing special.
