I actually had a busy day yesterday, and I didn't have free time until about 9:00 last night.  I then rummaged through the DBD to see if any interesting Cal related news stories were posted.  Apparently, there was a lot of boredom yesterday.  But do not fear, I found this website a week or so ago, which is great for killing time.  It is basically a bunch of trivia quizzes.  Below or a few of the quizzes, I have a preference for geography, but they have sports, popular culture, and a bunch of other categories (my scores to the right):

1.  Naming every president:  41 of 44

2.  Naming every Simpsons Character:  55 of 63

3.  Most spoken languages:  13 of 20

4.  Speed geography:  got through 22 of 50

5.  Most Populous Countries:  25 of 25!

6.  Beer Consuming Countries per Capita:  20 of 20!

7.  Richest Countries:  27 of 30, though I knew number 1, I simply didn't know how to spell it.

8.  Naming the 50 States:  50 of 50

9.  Winningest College Football Teams:  25/26

10.  Identifying Cities by Pre-WWII Photos:  16/20

Anway, there are a bunch here:  http://www.sporcle.com/

Enjoy!
