Taking the high road! On the next episode of Keeping Up With the Kardashians, family matriarch Kris Jenner incurs the wrath of her estranged husband, Bruce Jenner, when she's caught getting high on pot with her mom, M.J. Shannon, in their house.

"We think it would be a good idea for M.J. to try out some MJ," she quips. "You know what marijuana is?" she asks the former Olympian, whom she nicknames "Mr. Buzzkill."

Kris and her mother can't stop laughing at themselves, but Bruce is not amused. "As usual, he's not happy with us, because we're having way too much fun," the momager explains.

He proceeds to lay down the law, telling the giggly pair to shape up before daughters Kendall and Kylie, 18 and 16, return home. "I want that s--t out of the house before they get here," he reprimands them.

Watch the "high" jinks above! Keeping Up With the Kardashians airs Sundays at 9 p.m. ET/PT on E!.
