No psychology, really — reverse or otherwise. I was just tacitly inviting Meditations on the topic.
I suspect this is the highest profile reference to Perl in popular culture in a long time — maybe ever. You don't just see a snippet of Perl code on a computer monitor — which you do — or a Perl book on a shelf in the background. In an important scene at the beginning of the film, Perl is prominently mentioned in the voice-over narration of the Mark Zuckerberg character reading Zuckerberg's own real online diary.
To me, it's odd that on the preeminent social networking Web site for the Perl community, PerlMonks, there's no discussion of this reference to the Perl programming language in the movie that was ranked number one at the box office in the U.S. this weekend.
