When the League is preparing to revive Superman, Barry jokes that he hopes it doesn't turn out like Pet Sematary, the famed Stephen King novel (and movie), which of course revolves around dead animals being brought back to life, but bringing some nastiness back with them.

Once Superman is brought back to life and begins lashing out at the League, Wonder Woman tells her comrades, "He's confused, he doesn't know who he is", at which point Barry hilariously quips, "Pet Sematary."

Ezra Miller's hysterical comic timing makes it one of the funniest lines in the movie, even if it's a pretty obscure reference for younger and more mainstream audiences.
