One quick glance at their Instagram pages is all it takes to know that Kendall and Kylie Jenner are the queens of "age inappropriate."
Usually that means that Kendall and Kylie are partying with older men or posting pics of themselves in various states of undress despite the fact that they're still in their teens.
Ya know...the sort of thing that would shock most parents who aren't named Kris Jenner into banning their daughters from the Internet for life.
However, a photo that Kylie posted on IG earlier today is unexpected (and arguably unsettling) for totally different reasons:
That's Kylie and Kendall posing with noted German sex therapist Dr. Ruth Westheimer. No, really. Check Dr. Ruth's Wikipedia page if you don't believe us. That's her job title.
Dr. Ruth is something of a celebrity, and she apparently crossed paths with the Jenner girls at a recent event so it's not all that strange that they'd pose for a photo. Until you look at the rest of Kylie's page...
These girls meet celebrities constantly, yet Kylie rarely posts a photo of a famous face with a shout-out in the captions, as she did for Dr. Ruth.
We'll leave you to speculate about why two teenage girls would be so psyched about meeting a sex therapist while you peruse this gallery of inappropriate pics of Kendall and Kylie. Just don't blame us if you end up on some watch list:
