Paul and his wife are driving down a busy street. They stop at a crossing and a car pulls up beside them and it stops too. The driver rolls down his window.

“Excuse me, sir,” he says, “But can you please tell me where the main street is?”

“Sorry, sir,” answers Paul, “But we don’t have Main Street in this city.”

The fellow looks at Paul strangely and then rolls up his window and drives away.
