In the grand tradition of Freaks and Geeks and Arrested Development, Party Down is a canceled-before-its-time TV comedy that's earned a devoted cult audience. Airing for just two seasons on Starz, Party Down tracks the workplace doings of a Los Angeles catering crew staffed with aspiring actors, writers, stage moms, and has-beens—and the show reliably stumbles into deep, itchy hilarity. Tonight's TV Party features four episodes handpicked by series cocreator Rob Thomas. (Central Cinema, 1411 21st Ave,, 7 pm, reserve a seat with a $5 food/beverage voucher, all ages)
