I got this from Heather Kliner who received it from Carrie McKinley. I also received it from Scarlett and others.

There was this guy and he had a girlfriend named Lorraine, who was very pretty and he liked her a lot. One day he arrived at his job to find a new girl had started to work in the office. Her name was Clearly and she was absolutely gorgeous. He became quite besotted with her and after a time it became obvious that she was interested in him too. But this guy was a loyal man and he wouldn’t do anything with Clearly while he was still going out with Lorraine. He decided that there was nothing else to do but to break up with her and get it on with the new girl. He planned several times to tell Lorraine but he couldn’t bring himself to do it. One day they went for a walk along the river bank when Lorraine slipped and fell into the river. The current carried her off and she drowned. The guy stopped for a moment by the river and then ran off smiling and singing…

“I can see Clearly now Lorraine has gone”
