This isn't like that "challenge for the rights of master" thread a few years back, but what do you know way too much about? I see this thread as a way for people to say "Man, I've always wanted to know more about [Insert Topic Here] and [Insert Poster Name Here] knows a lot about it, so I can ask them any questions I have!"


For instance, Gwahir could run circles around nearly everyone in Buffy-verse knowledge, and Tengu can run laps mentally about Star Wars.


I personally know a lot about Terminator, Predator/Alien, and comic books. What do you consider yourself an expert on?
