A Polish immigrant went to apply for a drivers license. He sent off all the forms and all was fine but he was asked to take an eye test.

So off he goes and gets himself an appointment the same day, and sits down in the examining chair.

The optician showed him a card with the letters

'C Z W I X N O S T A C Z.'

"Can you read this?" the optician asked.

"Read it?" the Polish guy replied, "I know the guy."
