88. 'Party Down'
The great Lizzy Caplan and Adam Scott headed up a crew of caterers – you know, failing actors – who served hors d'oeuvres and despaired at porn-star conventions, high school reunions, and other disasters. This masterwork never got anywhere near the attention it deserved. But for both laughs and pathos, the episode when they cater Steve Guttenberg's 50th birthday party can hold its own with any half-hour of TV comedy ever.
