There are two Kiwis (Kiwi = NewZealander for those who are not in the know) bought two horses and rides them into Auckland town center. They both wants to get some lunch in the pub.

"So, how do we know who own which horse?", ask one of them.

"Simple, we cut a bit of my horse's ear, and we know the one have one shorter ear is mine", said the other.

So they did it and went into the pub to have lunch. But when they are eating, their horses got into a horse fight and bit each other's ears off..
When the kiwis walked out, they could see that both horses have very short ears. Thus they debated who owned which horse, and punches were thrown at each other. Some bystander called the police.
When asked by the policeman, they told the story and asked the policeman to be the judge who own which horse.

"Look", said the policeman, "cant you see..., the back horse is bigger than the white one..."
