I'm not entirely sure the following can be legitimately defined as "Sketch Comedy." As a fair amount of my peers can attest to, this clip from season two of Portlandia feels more like an Unsolved Mysteries-styled dramatic re-enactment, capturing the slow descent into mania that has afflicted many viewers of fine television since 2004:
Presumably, the end of this video is a springboard for related sketches featuring writer/producer/director Ronald Moore, actor James Callis (Gaius Baltar), and Edward James Olmos (William Adama), who have told fans they've shot footage for upcoming Portlandia episodes.
Also - I get the sense neither Carrie Brownstein or Fred Armisen have actually watched Battlestar Galactica because the first thing people do upon finishing the finale is to stumble towards the nearest online-enabled device within reach and fight with people on the internet about it. Much like what will probably happen in the comments section below.
Portlandia season two premieres January 6th.
