Arnold Schwarzenegger got a literal kick in the pants at the Arnold Classic Africa event in Johannesburg on Saturday. In a video shared on Twitter, a man can be seen rushing up behind him and kicking him in the back. He then stumbled forward as security swooped in and snagged the perp.

“Thanks for your concerns, but there is nothing to worry about. I thought I was just jostled by the crowd, which happens a lot,” Schwarzenegger later tweeted. “I only realized I was kicked when I saw the video like all of you. I’m just glad the idiot didn’t interrupt my Snapchat.”

He then took the opportunity after going viral to push his sports biz, tweeting: “Do me a favor: instead of sharing the video of the guy who wants to be famous, watch some of our @ArnoldSportsathletes like this young hero proving that fitness is for everyone who deserve to be famous. They’re on my Snapchat.”

Schwarzenegger continued: “We have 90 sports here in South Africa at the @ArnoldSports, and 24,000 athletes of all ages and abilities inspiring all of us to get off the couch. Let’s put this spotlight on them.”
