Basically what I mean by something Joker related: If something were to happen before Friday this week and involve Joker, then it could be going back to #1. And I don't mean violently, I mean online. This week in Joker-related stuff, there was mainly the Miley Cyrus IG post and Starbucks secret menu item, and that's been it so far.
Last week, SNL did the Joker parody with Sesame Street and it was hilariously good. Also there was Hugh Grant talking about the movie (although his experience wasn't pleasant) and also Pete Davidson mentioning it on SNL. So anything social media and all from this week can cause Joker to hit #1. But for now, it's not going to happen. However, the drop wise may not be a whole lot.
