Even though she made the mistake of spending a decade of her life cleaning up Scott Disick's vomit, Kourtney Kardashian still has a lot going for her.

She has three lovely kids, enjoys a "career" that requires her to do literally nothing except live out her lavish life in front of a camera crew, and probably owns about a dozen pairs of shoes that cost more than your car.

But apparently, there's one area in which Kourtney is sorely lacking.

It seems the girl can't play a prank to save her life.

In a preview clip for this week's episode of Keeping Up With the Kardashians, Kourtney and Khloe attempt to punk a Sleeping Kendall Jenner.

Their plan is at once simple and intricate:

Kourt and Khloe plan to cram some chocolate in Kendall's butt crack in hopes of making the poor girl think she "sharted" herself in her sleep.

Like we said, not a terribly complex plan, and if executed properly, it probably has an amusing payoff.

But that's the problem--you've got a couple first-timers attempting a prank with a pretty high degree of difficulty.

Granted, we've never tried to put food in a sleeping person's ass, but we imagine it's pretty hard to do so without waking them up.

This is a classic case of flying too close to the sun and Kourt and Khloe pay for their hubris in the end.

It's like a Greek tragedy, but with butt chocolate.

Next time, just draw dicks on her face and be done with it.

We kid. Nothing ever happens on this show.
