Some caltech students did something like this with a mcdonalds contest back in the seventies, only they did it with a lineprinter in the campus computer center as well as a hydraulic paper cutter at a commercial print shop. Caltech got a lot of really bad press as a result so when they inevitably won most of the prizes they donated them all to charity. It is for this specific reason that these contents now say "one entry per visit".
