Have you ever wondered why Netflix has that countdown between episodes? Well, that worrisome thought will never interrupt your binge-watching again.

While writing his weekly “Thank You Notes,” Jimmy Fallon finally explained the reason for the streaming service’s timer. Apparently, Netflix does it just to mess with us. The company knows we’re going to keep watching, and they want us to know that they know.

For the record, Netflix does give you the option to opt out of automatically playing the next episode. It’s currently available on a number of devices.

But if you haven’t heard, the new season of “House of Cards” is coming out next month, and Netflix has plans to premiere up to 20 new shows or new seasons of original shows a year. So really, why bother?

“The Tonight Show Starring Jimmy Fallon” airs weeknights at 11:35 p.m. ET on NBC.
