Many anime series tend to employ running gags, like the bookstore employees in Lucky Star, Edward being sat on by big dogs in Full Metal Alchemist, or Kakashi openly reading adult books in Naruto. Jujutsu Kaisen is no exception to this lighthearted trope, with protagonist Yuji Itadori's love for actress Jennifer Lawrence on full display. And this wasn't just a one-time deal either—it was referenced multiple times in Jujutsu Kaisen, with or without Yuji Itadori being asked.
