I’ll go first: r/kitty. One of the hundred grillion cat subs back on Reddit, the culture in this one was you posted a cat picture, and the only word allowed in the title or in any comments or replies was “Kitty.”
Someone is using that subreddit for covert communications, I just know it. Either on the level of “if u/PM_me_your_nostrils posts an orange cat, we attack at dawn!” or there’s some steganography going on with the pictures, but that subreddit was too stupid to be as active as it was.
I once read a beautifully indisputable piece on how Jar Jar Binks is a highly skilled Sith Lord. It’s all a front!
As memey as the whole theory is, I like to mention that George Lucas was influenced by a lot of classic scifi. He was almost certainly aware of the famous Foundation novels. In the second book, the comedy relief character turned out to be the secret villain leading the evil empire and who had mind control powers.
