NewsRadio, Season 2 Ep. 10: XMas Story
The main plot, largely centered on the boss getting presents for the office, seemed predictable at first, but the writers sidestepped the obvious twists. There was also a subplot involving Phil Hartman and a Salvation Army Santa that almost had me falling over laughing.
The episode was dark without being depressing, and funny without feeling pointless. It wasn't the greatest Christmas special ever, but it's definitely worth adding to your holiday set list.
