Have you seen the new Joker movie yet?
As far as I’m aware after watching it, The Joker does not have a library card. This is just one of the many profoundly sad things that you can expect from Joker. I am hopeful, however, that in the next movie there will be at least somewhere between three and 56 scenes dedicated to him visiting his local library.
If they do decide to feature a library in the next Joker movie, here’s what I envision he would check out with his library card.
