In Sunday's episode of Keeping Up With The Kardashians, Kim Kardashian and Kourtney Kardashian gross their family out when they profess their wish to eat placenta.

In the preview clip below, the Kardashian sisters have a family dinner with Khloe Kardashian, Scott Disick, Bruce Jenner and Kris Jenner. A heavily pregnant Kim asked the family chef Sharone if he has ever cooked placenta and added, "They say you can eat them."

Sharone said he has never cooked it but his wife has eaten it.

"It's supposed to be good to ways," he explained to Kim. "One, for postpartum and two, for menopause."

After he mentioned the word menopause Kris paused from eating her meal and looked up at the chef in disgust. When Khloe cheered about the idea, Disick suggested that Kim and Kris "split" the placenta after Kim gives birth.

Kris laughed so hard at the idea she said she "snotted" herself while Kim said she has read books on how to cook it. When the family expressed being grossed out about the idea -- Kris said she lost her appetite over the idea of eating her daughter's placenta -- Kourtney defended Kim. 

"It is the most disgusting thing I ever heard," Kris told Kim.

Kim said she was disappointed that no one else besides Kourtney agreed with the idea. She told the camera in her confessional, "I just think everybody is being very weird and close-minded. Except for Kourtney, she gets it."
