A married couple were asleep when the phone rang at 2:00 in the morning.

The wife (undoubtedly blonde), picked up the phone, listened
a moment and said,

"How should I know, that's 200 miles from here!" and
hung up.

The husband said,

"Who was that?"

The wife said,

"I don't know; some woman wanting to know 'if the coast is clear."
