This seems absolutely, medicine nurse positively unnecessary, but for some reason we still watched it. Khloe Kardashian and her famous sisters Kim and Kourtney Kardashian and half-sisters Kendall and Kylie Jenner launched their respective new apps on Monday, Sept. 14, and in Khloe’s first video, the reality star is teaching fans how to place cookies in a jar — literally.In a segment titled “KHLO-C-D,” the recently slimmed-down Keeping Up With the Kardashians star revealed that after she posted a photo of a bouquet on her Instagram, fans became obsessed with her perfectly aligned cookie jars that were visible in the background.

“I love them, but I’m also crazy,” Khloe said in the video. “But I love to know that the rest of the world is as crazy and organized-obsessed as I am…You say OCD is a disease, but I say it’s a blessing.”

In the video — in which she demonstrates stacking more than four boxes worth of Oreo cookies into a 2-gallon jar — Khloe blames her mom, Kris Jenner, for copying her household skills.

“I can’t handle my mom’s house because she copies every f—king thing I do and no one gives me credit,” she laments. “I taught her everything she knows.”

As for her sisters, Kylie posted a video addressing boob job rumors, crediting a push-up bra instead while Kim also lent fans insight on makeup technique “strobing.”
