Here’s a little bit of keeping it in the family. He’s not credited in the episode, and not even at IMDB, but according to Stuart Manning’s indispensable The Worzel Book, that’s Sean Pertwee as one of the silent guard scarecrows who are about to throw Worzel onto the compost heap. He was about 17 at the time and didn’t have a credited role for another six years after this.
“The Jumbly Sale” is another one with Aunt Sally being remarkably cruel and hurtful to Worzel, but her appearance in the story is pretty hilarious. Throughout the first three series, Michael Ripper’s character of Mr. Shepherd has been insisting that his aunt sally is a valuable antique, but he’s finally given up trying to sell her and is tired of her constantly moving around and ending up where she isn’t meant to be, and has donated her to the village’s charity garage sale. She gets sold to a local fellow called Gypsy Joe, “rescued” by Worzel, and, like a bad penny, ends up at Mr. Shepherd’s house again. This time, he locks her in the attic, hoping that the blasted thing can’t cause him any more trouble. Doubt that!
