One day, a motorist was arrested for driving at a very high speed. He was presented before the judge.
The judge asked him, "Do you want to say something?"
The motorist said, "Sir, I am innocent."
The judge asked, "Didn't you read the traffic signboard, 30 km/hr?"
At this, the motorist said, "Sir, how could I have read that message when I was driving at the speed of 60 km/hr?"
