The 'This is Us' season premiere had the perfect Kardashian pregnancy joke and fans lost it

Warning: There are spoilers ahead for "This is Us" season two.

The season two premiere of "This is Us" brought back Randall's birth father and shined some light on Jack's mysterious death. But it also gave us a Kardashian joke that couldn't have come at a more perfect time.

Early into the season two premiere, Sophie (Alexandra Breckenridge) laments about not being able to join Kevin (Justin Hartley) out in Los Angeles while he's on set a new movie. Not only will she miss out on celebrating his 37th birthday, but she'll also miss out on spotting a Kardashian.  

Kevin cracks a quick-witted joke to cheer her up.

"The Kardashians aren’t going anywhere," says Kevin. "I promise — They're like gremlins. By next week, there'll be like a bazillion more of them."

The joke came hours after reports that Khloe Kardashian is pregnant with her first child. That news followed earlier reports from last Friday that her sister Kylie Jenner is pregnant, too. Kim Kardashian is expecting her third child with Kanye West via surrogate in January. So, yes, there could be quite the Kardashian boom at present.

Fans were quick to call out the one-liner:

For the record, E! is part of the NBCUniversal family if you want to start to go down that rabbit hole. But this is most likely a conveniently-timed joke. The show was filming over the summer. 

But hey, maybe next week's episode will predict something about the next "Star Wars" movie.
