An unusual video has emerged of a huge snake slithering out of a man's trousers as part of a bizarre stunt.

The footage, captured last month in the Bolivian jungle, shows a man dressed in a camouflage suit with his back to the camera, urinating on the ground before he turns around to reveal a huge boa constrictor slithering out of the top of his trousers.

According to the filmer, the men were on a survival training expedition in the jungle when they decided to lighten the mood.

The subject of the video has several years experience handling dangerous and poisonous animals in the region and, according to the men involved, the wild snake was not harmed in the stunt.

"The presence of a boa constrictor at your side will help you urinate better and will also prevent small rodents from entering your clothing. But, from time to time, do not forget to air your snake" the filmer later wrote online.
