One day Jim was sick and stayed at home in bed. Not long after his wife left for work, he was awoken by hearing running water. He finally figured that it seemed like something downstairs running. So he finally conjured up enough strength to get himself out of bed to investigate, and it was then he stumbled onto the cause of their really high water bills. Apparently this was happening all day long when they were not at home.
He called his wife home, and then knowing that few people would ever believe them, he and his wife video taped a segment of the 'problem' for all posterity so as to have a film of this unbelievable 'leak' -- see attached video.
