what if i told you.... / you didn't have to dump ice on your head to donate to charity
A Matrix Morpheus meme.
Matrix Morpheus is Laurence Fishburne's character from The Matrix (1999), the mentor in mirrored sunglasses who reveals what's really going on. Captions start with "What if I told you" and end with a statement that's meant to blow your mind - or just state the obvious. It's the meme for revelations.
