The challenge is becoming ever so popular with everyone because it's fun to do and looks cool after.
Early November, while at a show in Denver, SremmLife brothers Swae Lee and Slim Jimmy challenged their audience to stand still like a mannequin while the camera films them to their song "Black Beatles." After successfully completing the challenge with the audience, it then went viral and the rest is history.
This stunt grew in popularity and caught the attention of pretty much everyone, even Paul McCartney.
