Stick with Me Shaun the Sheep : Season 1 Episode 36

Everything must go when the farmer sets up a stall by the side of the road and leaves Bitzer in charge. The lazy sheepdog soon tires of his role and gives Shaun the job. He proves to be a much better salesman than Bitzer and the flock are only too happy to get stuck in, selling pretty much all the farmer's worldly possessions.
