Ever have a few minutes to kill when you are on line? I've looked for a good trivia site to test my brainpower, and sporcle.com is definitely it.
The format is along the lines of coming up with parts of a list. Taking sports, can you name all of the Norris Trophy winners? Big Ten schools and their cities? The pitchers who have 3,000 career strikeouts?
There are tons of other categories, though. Presidential election losers. Rivers. Languages. Most common English words (hard!). Counties of Ireland (not for Americans). And so on. Once you are done and you are finished slapping your head ("How did I forget Buster Douglas?"), the game tells you what percentage of testers got a particular answer right, and where you rank in the general population.
