Random Knowledge?

So... I was wondering, while I was shoveling snow (yes, I think of linguistics while I shovel snow), what do you call it when someone knows a lot of random stuff about random things?

Terms I've heard (from myself and my family, I'm from Michigan but most of my family is from New York City):

- trivia knowledge
- trivial knowledge
- Trivial Pursuit knowledge
- Jeopardy knowledge
- Bathroom Reader/Uncle John knowledge (from the Uncle John's Bathroom Reader series of books)

What do you call it, and where are you from?
