In a new promo clip for the 2014 MuchMusic Video Awards, which the sister duo will be cohosting together, the E! stars try their hardest to scare each other with gruesome tricks.
First, Kendall walks into a room while playing on her phone. She's startled and lets out a gasp of surprise when she comes across her little sis lying lifeless on the floor covered in blood and seemingly dead.
"Nice try," Kendall quips before hopping over Kylie's body and walking away.
Next, Kendall tries to get Kylie back by sneaking up on her with a giant chainsaw, but Kylie is unimpressed.
Lastly, Kylie unveils a plate of food only to uncover a fat dead rat on a silver platter. Kendall and Kylie burst out laughing before the message "Save your screams" flashes across the screen.
Kendall and Kylie are set to host the annual Canadian awards show on Sunday, Jun. 15. Lorde, Ariana Grande, Imagine Dragons and Ed Sheeran are set to perform during this year's MuchMusic Awards with Chloe Grace Moretz, Kellan Lutz, Jena Malone and Tyler Posey presenting.
