The Blonde's Cheating Husband

A married couple was asleep when the phone rang at two in the morning. The blonde wife, 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!! It was some woman wanting to know if the coast is clear. How should I know!?”
