I wouldn't necessarily call it random fact throwing, though sometimes my listeners don't always connect the facts. Someone will be having a conversation, and I'll usually wait until they're done with their sentence, then say the old "Did you know...?" routine. I'm known around the office as the human encyclopedia. Most respect me for it, although I think some are definitely weirded out by it. *shrugs* I just like knowing things, and if I don't know something, I go nuts until I do a quick Google research on the subject. I don't know how I lived before the internet! LOL!
