Novelty library marketing to college students

From the most recent American Libraries Direct email (2/6/08):

"For the past seven years, the Lafayette College Libraries have been creating and mailing humorous collectible postcards to students as a way of publicizing PRA (Personalized Research Assistance) sessions, which are essentially individual research consultations with reference librarians..."

"...The first PRA postcard came about informally. As a joke, one of the librarians mocked up a spoof of the film Conan the Barbarian and the tagline, 'Make an appointment with a reference barbarian today!' It was basic humor, it was typical of the library staff at Lafayette, and it just kind of stuck. "

There's a gallery of the postcards at http://ww2.lafayette.edu/~library/pra/gallery.html. The one I almost choked over was the take-off on the Wizard of Oz (Wizard of PRAs) with the tagline, "We can't give you a brain...".
