Media Mind Control: Subliminal Messages

If you don't get one, check the youtube comments at the link.
A good hint when observing any media: always look at the spaces in between, always look at the background, the decorations and the clothes, etc - never just at the main thing alone, like the talking heads on tv for instance. You'll find watching movies and series suddenly becomes much more interesting (if you have a basic grasp of symbolism, if you don't yet, it's fascinating to dive into!)
