Kendall Jenner and her sister Kylie Jenner recently appeared on the TBS hidden camera show ‘Deal With It’ to help Howie Mandel pull a prank on an unsuspecting person. But it was the Jenner sisters who ended up being the butt of the joke.

While Kendall and Kylie watched and listened via remote in the backroom, an unsuspecting woman was on a date with a man who was in on the joke and knew the Jenner girls were watching. As they were being taped, the man was secretly prompted by the Jenner girls to say to his date, “Admit you’re crazy like the Kardashians.” Instead of agreeing, the woman  responded with, “No, I’m not slutty.”

Kendall and Kylie appeared very shocked to hear this revelation and gave a priceless and synchronized reaction.

Really?! That’s surprising to hear?

The sisters then decided to make themselves known to the woman who just insulted their entire family. Watch what happens in the video clip below:
