That's the very reason I'm in this "Batman group". You know, some people are the hardcore Star Trek followers, others Star Wars, etc.
To further your point, I have a few examples myself. In my math class I had to write an essay (I know, he assigned us essays, in a math class!? lol) about a mathematician. 800 words! I'm not a math major, how in the heck would I know that!? Well flipping through the book I found a pic that caught my eye. It was the same poster Jervis Tech had in his office of the Mad Tea Party. I found out that Charles Dodgson, the creator of the Alice stories, is a mathematician, and by doing a little research fueled by curiosity, I learned a lot!
And in my psych class, I already knew about Multiple Personality Dissorder completely because between BTAS and TNBA, Harvey Two Face is an excellent, if not the best, example you could come up with!
