Reminds me of one of the textbooks used in a Logic course I had many years ago. On the cover is a photo of some people having a picnic in a city park. There's an official sign saying 'No cars or trucks OF ANY KIND allowed in park'. Parked right behind the sign is ... you guessed it ... a police car.

It also brings to mind Lewis Carroll's Through the Looking Glass:

'When I use a word,' Humpty Dumpty said in rather a scornful tone, 'it means just what I choose it to mean—neither more nor less.'

cheers,
