There's an old blonde joke...
The blonde was bragging to her friends that she knew all the state capitols.. go ahead ask her anything... Her friend asks, what's the capitol of Minnesota? She things for a second... and says "M"...
Putting on my Ugly American hat for a moment...
Other than for Jeopardy, and other trivia games that make use of this knowledge in my head... Unless you are a resident of New Jersey, why is it important to know that the capital is Trenton?
I woudl agree being informed of world events is important... being informed of local events is equally important... but isn't know that Georgia has more square footage than Florida has, just trivia? Does that knowledge actually serve a useful purpose?
