18 times 'The Simpsons' accurately predicted the future

Nearly 19 years ago, an episode of "The Simpsons" predicted that Donald Trump would one day become US president .

And this wasn't the only time the writers have managed to predict the future.

The most recent prediction to come to light is from an episode two years ago, which preempted Daenerys Targaryen's big plot twist on Sunday night's penultimate episode of "Game of Thrones."

"The Simpsons" has been running for over 27 years, so it's inevitable that some themes that crop up in the show might occur in real life. But some of the plotlines are eerily close to events that have happened throughout the world.

We've listed some of the strangest predictions the cartoon's writers have made since the show's launch in 1989, from Homer discovering the Higgs boson to animators drawing The Shard in London almost 20 years before it was built.

Edith Hancock, Amanda Luz Henning Santiago, and Carrie Wittmer contributed to previous versions of this post.

Here are 18 times "The Simpsons" predicted the future, in order of their appearance on the show:

1. Three-eyed fish Season 2, Episode 4

In this episode from 1990,Bart catches a three-eyed fishnamed Blinky in the river by the power plant, which makes local headlines.

More than a decade later, a three-eyed fish was discovered in a reservoir in Argentina. Strangelyenough, the reservoir itself was fed by water from a nuclear power plant.
