For the brief few seconds between his initial reaction and everything else that followed, I genuinely believed Fugger's response would center around Moe's comment about being "dead in a shallow grave" and result in a similar misconception which he had back in Killer Bars. Maybe leading to some kind of payoff to the mobster persona he's been putting on all episode.
Holy shit, that breakdown was so out of pocket it's borderline Shakespearean.
