Boy photobombs reporter's live cross with surprisingly good dance moves

A young boy has been filmed dancing behind an unwitting reporter during a live cross on the historic floods sweeping through Louisiana.

WAFB-TV reporter Justin Jaggers was in the middle of warning people against travelling during the floods when a boy in a bright red shirt appeared in shot before stopping when he noticed the camera.

The unknown boy then spent almost a minute busting a move behind the reporter.

As the reporter turned to point behind him towards the increased traffic in Baton Rouge, the quick-thinking boy ended his dance by placing his hands on his hips before walking away as if nothing had happened.

There hasn't been much good news coming out of Baton Rouge lately, with the floods killing eight people and damaging more than 40,000 homes.

Floodwaters are so bad in the town of Watson, not far from Baton Rouge, that caskets have been rising from their graves.

US President Barack Obama has issued a disaster declaration for the state, where emergency crews have already rescued more than 20,000 stranded residents.
