Khloe, Kylie, Kendall and their friends were certainly having a lot of fun during the Kardashian family vacation to the Dominican Republic on "Keeping Up With the Kardashians" (Sun., 9 p.m. ET on E!). But in one instance, it was at the expense of their mother, Kris Jenner.

It was a long prank, as the girls dragged Kris out of bed, and on a carpet through the house until they threw her in a shallow pool of water. Jenner was wearing a robe, adding to her embarrassment in the moment. To make matters worse, it looked like the tumble into the water might have broken her toe as well.

While the toe swelled and bruised, Kris kept her spirits up by dipping into the spirits. For the bulk of the vacation, fans were treated to a drunken Jenner, laughing it up and cutting loose like the normally over-stressed "momager" never really does. It was a lot of fun, but at the same time it looked like she might have been self-medicating to numb some of the pain in her toe.

"Keeping Up With the Kardashians" continues Sundays at 9 p.m. ET on E!
