Dave was sound asleep when his wife nudged him. “The phone’s ringing,” she said sleepily. “At this hour it must be for you.” She turned over and closed her eyes.

Dave rolled out of bed and tramped downstairs. A moment later he climbed back into bed and shook his dozing wife awake. “It wasn’t for me, after all,” he said.

His wife crawled out of bed, pulled on her robe, and was at the door when he mumbled into his pillow, “It was a wrong number.”
