The full trailer for Zack Snyder's Justice League debuted online today, and it brought a surprise for fans of The Joker, especially fans of Joker memes. The trailer revealed the first lines of a conversation between Jared Leto's Joker and Ben Affleck's Batman. Joker's first line begins with, "We live in a society," which should instantly ring bells for fans who have been inhabiting online spaces for years. The "we live in a society" meme was a format in which those proud of not fitting into said society would point out supposed hypocrisies or failings inherent in it. These memes would often be attached to images of the Joker -- usually, Heath Ledger's from The Dark Knight -- despite the Joker never having said: "We live in a society." The meme died down years ago, but folks started using it again ironically when Joker started releasing promotional materials.
