Let The Disick Kids Show You How To Dance To Demi Lovato's ‘Cool For The Summer'

They know how to get down.

As the eternal debate over which song is indeed THE song of the summer for 2015 rages on, we can at least be sure of one thing: No one can dance to Demi Lovato's "Cool For The Summer" (a serious contender for the title) like these kids can.

These kids, by the way, are Scott Disick's and Kourtney Kardashian's -- 5-year-old Mason and 3-year-old Penelope. Scott posted this video to Instagram Sunday night (Aug. 9) with the caption "Best thing ever," because it really is. There's something about the unrepressed childhood glee here that inspires us all to bust a move ourselves.

Clearly, the preferred way to groove to "Cool For The Summer" is by throwing your body backward and doing a sort of reverse-headbang, as Mason does, or by bouncing up and down and throwing a series of tiny punches, as Penelope does. Anything else is just plain wrong.

And that's good to know, since we've already covered how to boogie to Calvin Harris' "How Deep Is Your Love" (another legit option for song of the summer). Demi's jam needed its own how-to guide, which we're glad the Disick kids delivered.

Shout out to Mason's kid-sized Yeezus Tour baseball tee and Penelope's patterned pants. These kids already know how to dance and dress like bosses.
