INDIANAPOLIS, Ind. – A group of Indiana State Police troopers feeling nostalgic on the final day of the Indiana State Fair made a lip syncing video that has now gone viral.

ISP Trooper Brent Lemberg from the Fort Wayne post was patrolling the fairgrounds on Sunday with fellow troopers Jonathan Amburgey, of Fort Wayne, Jonathan Cole, of Peru, and Dustin Rutledge, of Peru.

As they were driving around in their golf cart, they decided it was the perfect time to break out the classic song “Summer Nights” from “Grease.”

Amburgey posted the video on Vimeo 15 hours ago, and it already has more than 20,000 views.

“The state fair is a time that we have the opportunity to interact with the public in a way that we normally don’t get to. We wanted to show people that we aren’t robots. We have a personality, we like to laugh, and most of all, we like to make other people laugh,” Amburgey told FOX59.

Amburgey said they don’t have a particular reason why they selected the song “Summer Nights.” He said they had been making videos all week, and they just selected the song at random.

Another video he posted on Vimeo is this rendition of “Bad Boys.”
