Finally finished season 3 this past weeks. Man, when I thought for a second that they actually killed off Colin Robinson, I got SUPER depressed. I should have known since they were still playing it off for laughs. Can't help but feel bad for Gizmo, though. My wife has never really watched the show with me, but she sat down for the episode where the vampiric council visited and ended up having an impromptu viewing of "dead" Nandor's penis. She was cracking up. She may want to go back and rewatch all 3 seasons with me now.
It and South Park are the only comedies my father, who is on the complete opposite end of the political spectrum, and I both enjoy.
