Internet freezes for 'mannequin challenge' craze
Videos of the challenge feature posing as mannequins in dramatic postures. They began to appear late last month online and by last weekend everyone from high school cheerleaders in Texas to the NBA's Milwaukee Bucks had taken part.
The Pittsburgh Steelers even enlisted the media's help in their version.
The challenge seems to have become a victory celebration of sorts for some teams. Texas Christian , Penn State and Clemson's football teams posted mannequin challenges after big wins Saturday.
The videos are set to the song "Black Beatles" by rap duo Rae Sremmurd. The group has taken notice, holding a live version of the challenge during a concert last week.
