I don't know! - Blonde jokes (75138)

A married couple was asleep when the telephone rang at two in the morning. The wife (undoubtedly blonde), picked up the telephone, 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'."
