Sunny Hare

One day my friend was driving his car. It was a sunny day and he couldn't see the speed limit sign. A policeman stopped him and asked why he was driving 80km/h in a 40 km/h speed zone. My friend replied that he couldn't read this sign because he had "caught a sunny hare"[been dazzled by direct sunlight]. The policeman took his details and he drove on.
A month later my friend was called to see the judge who said,
"I don't want to fine you. I just wanted to see who you were, because I've never heard such an answer given to a policeman. I know it's not true but I really liked your answer!"
So my friend was let off with a "first warning."
