During the family's trip to the Dominican Republic, the Kardashian family made a music video to Notorious B.I.G.'s Hypnotize that's got the whole group getting down!

From bikini shots of the family on the water and close-ups of Kim K's butt to Scott Disick rapping along in a headwrap and sunglasses, it's pretty obvious that this family knows how to have a good time, even at their own expense.

And the cherry on top? Bruce Jenner playing the bongos with Kris Jenner's behind! The men seem to like their share of derriere!
