Carlie has the most excellent idea of the week: Getting Supernatural's Jared Padalecki and Jensen Ackles (aka Sam and Dean Winchester aka pretty, pretty boys) on an ALA READ Poster.
In a nutshell, the reason is pretty obvious. Beyond the pretty, pretty. Sam and Dean routinely do research, using databases, historical records and libraries to figure out how to solve the supernatural mystery of the week.
So, go over to Pop Goes the Library for information on how to contact ALA to voice your support for the Winchester boys on a READ poster.
