Dr. Evil has Mini-Me, and now PRSA has Mini-Moo. That's right, PRSA is selling miniature versions of the cows that have invaded more than 20 cities across the nation. For dollars 500 you can buy a blank bovine, decorate it and auction it off at the Oct. 22-24 PRSA World Congress meeting in Chicago, the city that started the whole cow craze. Proceeds will benefit PRSA. No jokes about PR 'milking' situations, thanks.
