Yep...all I can say is keep practicing and answering questions. You'll get a lot faster with practice. When I 1st started answering questions I had no idea how some people got the answers so fast. Eventually I found a few ways to not only find the answers, but find them fast. Then they'll always be a question every once in a while that's nearly impossible to even find the answer. Sometimes with questions like that you can be the winner by being the only person to find the answer, even if it takes you 30 minutes. Keep practicing and you'll get better and faster.
I went to Superbowl.com and figured out which day was most common by looking at the boxscores page. When you're in the trivia blitz, quite often you'll have to be resourceful and look up answers. I have several sites that I frequent when trying to find answers to even the toughest questions here. Google is a nice way to start looking, but there are specific sites out there chock full of statistical anomalies and the like that assist me in the various cafe trivia blitz games.
