Ahh, sisterly love.
Khloe Kardashian thought it would be hilarious to embarrass sister Kourtney by filming her after a visit to the dentist. Well, Khloe was right her Keek video of Kourtney struggling to move her numb mouth is just too funny. Watch above!
"I've never laughed so hard," Khloe captioned the vid, which she took while the pair were at lunch in their local 'hood of Calabasas, California.
We hope Kourtney gets her back next time Khloe happens to need a check-up...
