6 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.

(Do keep a lookout of the rest of the degree in later post)
