As a young married couple, a husband and a wife lived in a cheap housing complex near the military base where he was working. 

Their chief complaint was that the walls were paper-thin and that they had no privacy. This was painfully obvious when one morning the husband was upstairs and the wife was downstairs on the telephone. She was interrupted by the doorbell and went to greet her neighbor. 

"Give this to your husband," he said thrusting a roll of toilet paper into her hands. "He's been yelling for it for 15 minutes!"
