The king of horror has apparently gone electric.

On Sunday, Stephen King tweeted to Elon Musk, telling him that he's "sort of liking" Tesla's silly "Fart" app.

While King didn't outright say he owned a Tesla, it's quite possible that he does, especially since Musk replied and thanked him for "owning a Tesla."

As far as we know, this could be two famous men just chatting on Twitter or it could be good old paid-for advertising, but it's still notable. King is famous for many novels, but one that comes to mind now is Christine, a story about a car gone evil. And with Tesla's ever-improving machine learning capabilities... well, you could certainly say that it's smarter than a 1958 Plymouth Fury, and by extension, more dangerous -- should it go sentient and decide to pursue evil.

As for the fart app King is referring to, it was added to Tesla cars in a Dec. 2018 update, alongside a new driving game and a special "romance mode." The app is more elaborate than one would assume, giving users a solid assortment of different fart sounds as well as the option to position fart sounds within the car.
