Kourtney And Khloe Kardashian Tried To Pull The Messiest Prank On Kendall Jenner

Everyone knows that the Kardashian-Jenner family don't play around when it comes to trolling each other, but things almost got messier than ever when Khloe and Kourtney tried to pull a prank on sister Kendall.

The trio headed off to Santa Barbara in a episode of KUWTK, where Kendall made the fatal error of being the first person to head off to bed. Cue Khloe and Kourtney conspiring about how to play a cruel trick on her.

Let's all get checking out an update from MTV News...

Because they couldn't think of any better prank than "covering her with baby powder," Kourtney took to Twitter to crowd source some of the best ideas out there. "Does anyone have any good prank ideas to do to a sleeping person? Me and @khloekardashian need help."

The pair struck gold when someone answered with a pretty horrendous suggestion. "Put a few squares of chocolate in their bum crack so it melts, and when they wake up they think they pooped themselves," one fan said.

Lucklily, Khloe and Kourtney were too loud sneaking into Kendall's bedroom, and she woke up in time before they managed to begin the task. Phew. 

"We wanted you to shart yourself," Khloé explained to Kendall, which prompted her to hit back with the insult that literally never gets old: "You guys are like, 12."

Um. Remind us to never have sleepovers with anyone ever again.
