VIDEO : Prankster Kourtney Kardashian Served Family a ''Placenta Dinner''

Kourtney Kardashian loves to prank her family, and we have proof. Back in 2013, Keeping Up With the Kardashians cameras caught Kourtney trying to serve her family a "beautiful placenta dinner." Kourtney even hired a chef to help cook up the placenta-filled meal for her family and friends! Only her sister Kim Kardashian and her then-boyfriend Scott Disick are aware that she's trying to serve human placenta. Disick didn't seem to feel bad about pranking their dinner guests. He told cameras that he wished he could warn guests, but added that everybody had done something to him at some point.
