What are cheese curds?

On the advice of Dennis York, do not pass up this column by ESPN's Bill Simmons on a recent trip to Wisconsin to catch some baseball and a football game. My favorite entry:

9:05 -- Reason No. 792 to love Milwaukee: During the seventh-inning stretch, cheerleaders dance to polka songs on top of the Brewers dugout. They're like the Bizarro Laker Girls.

Even if you're not a sports fan, this is great stuff.
