Fast National ratings for Friday, December 9, 2011.
 
CBS' latest airing of the seasonal classic "Frosty the Snowman" drew Friday night's biggest audience and best numbers among young viewers, but "Grimm" and "Dateline" helped NBC grab a small share of Friday victory.
 
Oh and "Chuck" had its best night of the season, which either is or isn't saying much, depending on your perspective.
