Who is the only guy that could make one of the best fighter walk-outs ever without technically walking out at all? David "The Caveman" Rickles, that's who. As soon as Rae Sremmurd‘s "Black Beatles" came on during Bellator 171, everyone knew Rickles was about to do the mannequin challenge. The surprise was that the Bellator staff and all of the fans lined up all along the ramp were in on it as well.
Viral movements are hard to understand. We could sit here and analyze the social folkways and mores of it all, getting lost in why this is a "thing" after the fact. But in that moment, a cultural event happened. An entire arena froze because it's just what you do. ...And Rickles did that. He commanded thousands of people without saying a word and they never even questioned it. That's cool.
