We guess the stars really are like us: They torment their sisters far after their teenage years are done. That’s our take-home message from Khloe Kardashian’s latest Keek, in which the reality star pokes fun at her older sister Kourtney after a trip to the dentist left one side of her mouth numb... and a little lopsided.

“I have never laughed so hard,” Khloe tells her 1.6 million Keek fans. In the (admittedly hilarious) video, the youngest Kardashian  sister laughs hysterically at Kourtney, who tries to hide her crooked smile from her taunting little sis — first behind a cloth napkin and then a menu. What, Kokes? You’ve never had to get your mouth numbed at the dentist?

“It’s not nice. Stop!” Kourtney protests as Khloe presses her to show the “Keekers” of the world her Novocained-up face. If you listen to just the audio, you’d swear it was two squabbling teenagers and not one 30-something woman and her nearly 30-year-old sibling. Once a bratty little sister, always a bratty little sister, right Kourtney?

On behalf of all the older sisters of the world, we sincerely hope Kourtney gets her revenge on Khloe next time she has to get a filling or a deep cleaning.
