In fact this website answers my questions above: http://www.bbc.co.uk/dna/h2g2/A370126
These odd creations serve little purpose other than to sit on the parcel shelf of a car and amuse or annoy the occupants of the vehicle behind while stuck in traffic!!
I guess a few people have been asking the same question….
But it gets better:
Place the ‘dog’ on the parcel shelf, or other convenient location, in a car. The changes in direction and velocity of the car in which the nodding dog is placed causes the head to oscillate at varying frequencies and in a variety of directions, producing the so-called ‘nodding’ effect. The placement of the dog need not be restricted to a car or other motor vehicle but if it’s situated on a windowsill or table it will need to be poked, prodded or flicked in order for one to experience the full nodding action.
I leave you with that thought …
