A funny video has emerged of a man jumping at his cousin with a clown mask to scare him.

The footage, shot on October 23 in Long Beach, California, shows Jalen Dotson surprising his unexpected cousin as he comes out of the changing rooms wearing a Teletubbies costume.

"My cousin has been afraid of clowns since we were kids, so it was only right that this be my first prank!" Doston wrote online.
