This text actually is from Merlyn LeRoy (who is none other than
Brian Westley) on usenet rec.puzzles in a post on 22 August 1992 and of
course I linked to his winning entries and the usenet post!

+Read the last line backwards! Credit goes to [Merlyn LeRoy (Brian

+those who have a harder time reading backwards it says: `Gary lent the rug`
