Picture this situation that you've driven too fast and police stops you and you KNOW you are in trouble. To turn the situation in your advantage you can do it by saying one single word. At first officer will be asking: "Do you know how fast you were going" or something equivalent which you can answer in a humble respectable way.
But when the conversation comes to the point when you are asked "Papers" you must turn your face serious and respond with a serious face
"Scissors, you lose"
If the officer has no sense of humour you can drive off a cliff and by dying you will evade any offences.
Please do not take any of the above seriously =)
