Harry Potter and the Prisoner of Azkaban Professor Sybill Trelawney (Emma Thompson)

Follow Your Heart, Your Premonition

Professor Trelawney is battier than the bats that surely live in Hogwarts towers. She teaches Divination, which puts her alongside colleagues like the Long Island Medium, and Miss Cleo.

Hermione believes her to be a total hack…and her wild behavior doesn't convince us any differently. But this doesn't stop her from delivering an eerily accurate prophecy:

TRELAWNEY: Tonight, he who betrayed his friends, whose heart rots with murder shall break free. Innocent blood shall be spilt and servant and master shall be reunited once more.

Hey, even a stopped clock is right twice a day.
