As everybody seems to agree, one of the best episodes of Family Guy. It's fast, it's silly and it dares to be tasteless. The plot may not be original (Passport To Pimlico springs to mind), but plots are never that important to this show.
The show is generally not renowned for its technical qualities or originality, and still only in its second season it probably didn't have the budget to experiment. But there's a scene here that totally amazed me with its combined use of visual intelligence and comedy timing. Once Peter has declared his house a separate country, the power company cuts off the electricity. Peter, Lois and Stewie have to make do with flash lights attached to their foreheads. What we get to see is just what appears in the beams of these three torches. While they talk, their eyes (light beams) wander off and you get two levels of conversation/thought. Stewie appears in the background and his actions are purely suggested by sound and his light beam. Whoever came up with this perfect comedy scene deserves a raise.
