Friends entertained wedding guests with an unusual parkour dance

A group of men and women surprised wedding guests with their acrobatic moves inside a church in Denmark.

A YouTube video shows acrobats from Team JiYo mesmerize the wedding guests with their nerve-wracking stunts.

Posted on September 19, 2013, the five-minute clip has been viewed almost 2.5 million times as of May 30, 2018.

"Flash mob at the wedding of our dear friends Helle and Jannik Baltzer Hattel. Thanks to everyone who contributed to living out this crazy and joyful idea," the group wrote about the video on their YouTube channel.

Performing to Bruno Mars' hit song, Marry You, the men showed off stunts like walking upside down and doing breath-taking summersault, among others.

One of the most nerve-wracking stunt was that of a man standing on another performer's shoulder.

It appears that one of the dancers was the groom. The video ends with the beautiful bride being led to the altar. The guests stand as she walks down the aisle, escorted by a man who may be her father.
