What if I told you / RWBY is what people who've never seen anime think anime is
A What if I told you / Matrix Morpheus meme.
This is Laurence Fishburne as Morpheus in The Matrix (1999), in mirrored sunglasses, about to change how you see the world. Captions start with "What if I told you" and end with a revelation - sometimes genuinely surprising, more often painfully obvious, like "you don't have to reply to every comment." It's the meme for truths delivered with far too much gravity.
