Summary[]
Sir Blur stumbles into a kingdom. A king is having trouble getting someone to marry his daughter because she's, to put it mildly, ugly. Guess who stumbles into the contest? Sir Blur was Famous Studios' answer to Mr. Magoo in that he was another nearsighted fellow who mistakes something or someone for something else. When King Arthur announces Tournament Day, with the winner earning the right to marry his fat, homely daughter, Sir Blur enters the competition.
