In the spliced footage, which was originally shown during a 2012 Keeping Up with the Kardashians special, “Dishing It Out,” where the family sits down to watch never-before-seen-clips together, Rob can be seen laughing uncontrollably, awkwardly dancing and even jokingly slapping himself in the face.
“This makes me ridiculously happy. @robkardashian,” Kendall, 19, captioned the post on Tuesday, complete with a heart emoji.
In the footage, a few other family members can be seen watching the funny scenes, including Kylie Jenner, Kourtney Kardashian, Khloé Kardashian and Caitlyn Jenner, back when she was known as Bruce Jenner before her transition from male to female.
While the 28-year-old has been recently spotted grabbing food or driving his car, he has maintained an extremely low profile and older sister Kim Kardashian West told Today‘s Matt Lauer in April that he may just be “going through a phase where he’s not comfortable in his own skin.”
