The Jack Russell - champion sheep worrier

So the topic of worrying sheep came up recently and the theory was put forward that Jack Russell's being a more intelligent breed of beast have their own style of worrying the wooliers. Apparently, they sidle up to the fuzzy ones under cover of dark and start telling them that inflation is up again, that the stock market is screwed and that the building industry is laying folks off left right and centre. That has them worried in no time at all.
