One night Rodney was driving home along a road he knew well.
When he reached the Stop sign he slowed down but did not actually come to a halt, whereupon a police officer pulled Rodney's car over.
'What difference does it make' said Rodney, 'slow down or stop'. 'I will give you a demonstration' said the officer and starting beating Rodney with his truncheon.' Now would you like me to slow down - or stop?
