We all know dances evolve over time, for better or worse. But when one guy was watching a beloved shuffle video, he was unhappy with the comments he saw: “LMFAO are way better, and why is he not in skinnies isn’t that what is meant for shufflin?”

Confused, he found a YouTube video that demonstrated the new so called “shuffle” and was shocked at what he saw. The kids in the video were mimicking LMFAO in “Party Rock Anthem.” He edited together a clip of the new shuffle with the original shuffle to show the difference and commented: “If you’re into lmfao shit leave a dislike and gtfo. And leave a like if you still know what real shuffle is.” This warning is followed by a video of an insane dancer who has moves like MJ at a rave.

Okay, point proven. But can’t we all just get along?

We know the big question on everyone’s minds this weekend is, what would an LMFAO song sound like if Bruce Springsteen and Neil Young sang it?

Not to worry, Jimmy Fallon has you covered. Springsteen and Fallon, er, I mean Neil Young, sang an acoustic version of the song “Sexy and I Know It.” Fallon donned a low hat and rocked out on the harmonica and guitar while Springsteen wore his infamous red bandanna and denim vest. They’re both totally sexy and they know it.

The song was performed to close out Springsteen Week on Late Night With Jimmy Fallon.

The other question on your mind is obvs, what would LMFAO sound like in the 1920s? Maybe I’m feeling sentimental becuase I watched The Artist today, but I kind of like this ultra cheesy Charleston version of “Party Rock Anthem.” The exact song they mashed it with is called Green Hill Instrumental.

LMFAO is NOT sorry for party rocking, even though they claim they are. In their new video for “Sorry for Party Rocking,” the third single from their sophomore album, they throw an epic party in a cartoon-like house.

Unfortunately their elderly next door neighbours (who appear to be SkyBlu and RedFoo under some intense makeup) are not so appreciative. The nearly 8-minute video includes a cameo from David Hasselhoff and lots of zebra print. The video is directed by Mickey Finnegan, who directed “Party Rock Anthem” and “Sex and I Know It.”"

I prefer when artists release videos like this, because they’re essentially short films with story lines — it’s much more interesting than a glammed-up singer lip-syncing on a stage. Plus the video features some pretty impressive dance moves.

This has got to be one of the coolest grandmother’s ever. Earlier in the year we saw her dancing to LMFAO’s “Party Rock Anthem” and now she pays tribute to Whitney Houston’s “I Wanna Dance with Somebody.” Her grandson Adam eventually joins the dance but it’s her moon walking, twists and turns that keep us watching.

So cute! The best part is, it was all her idea. I definitely hope I’m still shaking my hips like this at 90.
