Haha yes Mo. My husband used to laugh at the many triangular warning signs around our village about deer crossing. He thought it very funny to say, "Oh dear!" until I could stand it no more and the 'joke' was banned!
Here in Norfolk we have many mad signs, such as 'Turn Right Twice' and Nowhere Lane, not to mention Fustyweed, a village next door to ours.
Most folk take no notice, but I always smile a bit.
