Your Dog is Keeping me Awake
A college professor answered his telephone at 3:00 A.M. “This is your neighbor, Mr. Smith,” said the voice. “Your dog is barking and keeping me awake.” The professor thanked him kindly and hung up. The next morning Mr. Smith’s telephone rang at exactly 3 A.M. “This is the professor,” said the caller. “I just wanted you to know that I don’t have a dog!” (Encyclopedia of Illustrations #14107).
