The Coast Is Not Clear

It was two o’clock in the morning and a husband and wife were asleep when suddenly the phone rang.
The husband picked up the phone and said, “Hello? (Pause as he listens.) How the heck do I know? What am I, the weather man?” and promptly slammed the phone down.
His wife rolls over and asks, “Who was that?”
The husband replies, “I don’t know. Some guy who wanted to know if the coast was clear.”
