Seven Degrees of blonde - FIRST DEGREE

A married couple were asleep when the phone rang at 2 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."
