A police station gets two new horses and two cops are assigned to ride them. They go on a ride and come back pleased.
“This horse is great! I’ll always take this one from now on,” said the first cop. “My horse’s great too. So I’ll always take it, too,” replied the second cop.
“But, how would I know which is mine?” asked the first cop.
They thought for a minute and one of them came up with an idea. “Let’s cut off this one’s tail.” The other cop agreed and one of the horses lost its tail.
The next morning the police chief found out and got really mad. “You idiots cut off the horse’s tail!”
“But otherwise we couldn’t recognize them,” said the second cop.
“Can’t you see the black horse is a bit taller than the brown?!”
