I fucking love Metalocalypse. I love all the characters, but the dialogues between Skwisgaar and Toki are hilarious.
In "Dethwater" when they put Toki in the submarine's isolation chamber to record his rhythm part, the bit before he goes down into the water is funny: the operating guy says Toki will die without a safety briefing, and after Toki says "Skwisgaar, I thinks I needs that safety briefings" while his chamber fills with liquid, Skwisgaar says "the reason I comes down here is that we're all going to get some food, do you want some?" as Toki is getting increasingly anxious.
Comedy gold.
