I'm a veritable font of Godzilla/Kaiju lore as well as quite a bit about zoological/paleontological things. I've pretty much got a few animal encyclopedias memorized, or at least access to info on all sorts of things. Behavioral studies, bite forces, etc.
Pretty much anything you could find in a bad movie I've got down. Giant monsters, aliens, slashers etc.
I'm your go to guy for anything Zombie virus related.
I also happen to know a good deal about Higher Education in the state (and to a lesser extent the country) as well as a fair amount about politics and lobbying that sorta stuff. I was a lobbyist for the last couple years for student funding in my state and they sent me out to DC for a few days so it was kinda cool.
My working lore of Transformers grows steadily by the day, as does my info on the 40K universe
I think thats just about it. I'll condense the list for easy browsing:
-Higher Education in the US
-Bad Movie Monsters/Cheesy movies
