I saw this one forum contest once... Where the contest holder would clip a small portion of a picture, give a teeny tiny hint later on, and let people try to find what it goes to. It had to be some sort of a publisized picture, though. Not just some random picture on the internet. The one they chose was (I think) a picture of a chicken in a bucket, which was the old logo for some national chicken stand or something.

Maybe tonight we'll fly so far away... We'll be lost before the dawn...
