I was watching Season 3 Disc 4 (3:14 6b to be specific) and realised I had actually seen that episode on TV before. For most of a decade I had given up watching prime time TV (most TV in general except for some stuff on HBO, Comedy network, History channel, whatever is on at 1AM when I cant sleep) and it was kind of weird that I had seen this one and liked it without having a clue what the show was about or why things were happening.
