During the episode, something happens between Kris Jenner and her daughters and now they're seeking revenge on their mom.
The duo has Kris sit down and answer a series of questions. If she gets them right nothing will happen to her, but if she gets them wrong she'll get a water balloon dropped on her head or a pie thrown in her face!
The first question is about Kim's due date.
"What is my due date?" Kim asks.
"December the 24th," Kris says.
"Nope! Wrong-o," Kourtney says before a water balloon comes crashing down on Kris' head.
The second question is about Kim's daughter North West.
"What is North's middle name?" Kim asks in the exclusive clip above.
"South," Kris says.
That's wrong, so Kris gets a pie in the face!
"What is North's middle name?" Kris asks.
"North doesn't have a middle name!" Kim says.
"How many years has DASH been open?" Kim asks.
"Six," Kris says.
Wrong! It's 11 and Kris gets another pie to the face!
