Greater Vampire: “Punks, ho!”
Punk rock lives on! Vampires, being the most reliable creatures of Necropolis for many years, didn't disappoint in entertaining the audience. In the rare moments when they don't need to chop enemies into pieces and drink their blood, they entertain themselves and those around them with music. Using their brutal sword instead of a guitar, the guys put on a show, trying to imitate seasoned rockers.
Ugi, as a fellow enthusiast, you should know where this joke comes from – in my opinion, it's a direct reference to Arthas from Warcraft, who, even after becoming the Lich King, gives a rock or heavy metal concert at the end of the game. He even had it as his avatar on WWulf's site =)
By the way, I remembered that before the game was released, the developers showed several of these funny animations in previews and news. The shark one, for sure.
P.S. I understand. Ugi wrote the article, and Ego posted it here.
