In the middle of the 2017 season, the Houston Astros mascot, Orbit, began grooving to “Moves Like Jagger,” but what followed took everyone by surprise. Just as Orbit was about to face off with a security guard who seemed as unyielding as the Queen’s Guard, the man in the black uniform suddenly broke out into an electrifying dance of his own.

Like a scene straight out of a Beatles concert, the security guard stunned the Jumbotron crowd with his unexpected, star-studded, and wildly absurd moves, sparking cheers of delight. His grand finale—a full-body dive into the most jaw-dropping worm dance you’ve ever seen—capped off his impromptu performance and became one of the most viral moments of the 2017 ALCS. Since then, the video has racked up over 17 million views on YouTube.

However, this wasn’t the first time a surprising flash mob performance by a lone security guard shocked the crowd at a Houston sports event. The origins of this phenomenon can be traced back to a similar viral sensation from 2014, featuring the legendary dancing security guard, Willis Harris.

As a freelance security guard, Willis Clinton Harris is renowned for his ability to deliver outrageous dance routines, complete with campy splits and cartwheels. His iconic breakdancing video, “Work It Willis,” released over a decade ago, has since become an internet sensation, amassing 99 million views on YouTube.

Work It, Willis

Willis Harris has made a habit of going viral at sporting events, most notably during a Tampa Bay Rays game, with his infectious dance moves. The authenticity of these now-iconic viral videos was called into question after another unidentified security guard engaged in an impromptu dance-off with Orbit in 2017, three years after Harris’s initial showdown. When speaking with Fox, Harris hinted at a deeper connection with Orbit, calling him a “good friend” and teasing, “I’m not going to give away the secret sauce completely. We knew we’d be near each other, even if it wasn’t entirely prearranged.”

Regardless of how spontaneous Harris’s performances were, his interview with Fox makes it clear that his intentions were pure: “I’ve always loved the entertainment industry. Job security is number one, but entertaining the crowd is a close second. We should take every chance to make people laugh and remind them not to take life too seriously.”

Whatever the true story behind Houston’s dancing security guards, these viral videos are guaranteed to bring a smile to anyone’s face.
