A married couple is sleeping soundly.

Suddenly the phone rings at 2 o’clock in the morning.

The wife picks up the phone, listens for a moment and says,

“How should I know, that’s 200 miles from here!” and hangs up.

The husband, meanwhile awake, says, “Who was that?”

The wife answers, “I don’t know; some woman wanting to know if the coast is clear.”
