The Welsh shepherds and the flock of glowing sheep who have become the latest internet sensation

The hilarious 'Extreme Shepherding' viral by the 'Baa-Studs' team opens with a soundtrack reminscent of a spaghetti western before introducing key participants such as Emris 'the Electrician' and Gerry 'the Player'.

Armed with their shepherding skills, a cast of willing sheep, a small video camera and a generous dollop of technical wizardry the team set to work and let their imagination run wild.

Quirky virals to promote products over the internet are not new and recent ones which have been lauded include the drumming ape for Cadbury's and the impromptu commuter dance at Liverpool Street station for T-Mobile.
