*(Via LA Times) – In the 2½ years since Rae Sremmurd (the duo behind the #mannequinchallenge memes) broke out with the rowdy hit single “No Flex Zone,” this Southern hip-hop duo has established itself as a reliable source of renewable energy.

Its two studio albums — 2015’s “SremmLife” and August’s “SremmLife 2” — are full of boisterous thrills, with brothers Swae Lee and Slim Jimmy shouting sticky catchphrases over lurching beats. And the twentysomething rappers are even livelier in concert: Bouncing across the stage like each had inhaled a bag of Halloween candy, the two use those catchphrases to encourage their young fans to go wild (or turn up, as the saying goes).

Yet Swae Lee and Slim Jimmy had a different goal in mind Monday afternoon on the set of ESPN’s “SportsCenter,” and that was to go as un-wild as possible — to stand completely still while a guy with a camera weaved between them.

This, of course, was the Mannequin Challenge, the latest viral-video phenomenon after the Ice Bucket Challenge and the Harlem Shake. In this one, believed to have been started by a group of Florida high school students, participants are filmed frozen in place, in many instances as Rae Sremmurd’s song “Black Beatles” plays in the background.

Hillary Clinton took the challenge aboard her campaign plane. Rob Kardashian and pregnant Blac Chyna did it in a hospital delivery room. Even Paul McCartney joined the craze, tweeting a video that had him standing motionless with one hand on a piano. (“Love those Black Beatles,” the white Beatle wrote.)
