The 1st season does not quite have the same mixture of drama and comedy as the later seasons; it is more comedic. Likewise, the humor is a little less character driven here than in the later seasons. I.e. The season repeatedly puts David into explicit fish-out-of-water set-ups, i.e. Turkey hunting. The 1st on the whole is a funny diversion but it's best at setting the groundwork for later strengths of the show.
This episode is the first truly great episode of the series. It balances the humor and drama better than say "The Drip." The humor is a fully centered on the characters. The crucial scenes between David-Stevie and Alexis-Ted land a lot like the dramatic scenes from the later seasons. This is when the show found its groove. The 1st season is very good in itself but it setting-up 5 outstanding seasons after it is its prime virtue.
