The video was posted on YouTube on July 14, and is making its rounds on the Internet. It's not clear where the video was taken.
A groomsman and bridesmaid are seen entering the reception hall, ecstatically dancing their way to the dance floor. The man does some somersaults before he strikes the bridesmaid, knocking her over and causing a vase full of flowers to come tumbling down on top of her.
The groomsman then tries to get the woman up, and she falls again.
