Carpe Jugulum/YMMV


 * Complete Monster: The young Count Magpyr and his family are this. The old Count, despite everyone insisting, isn't.
 * Fridge Horror: Greebo's ferocity and capacity for destruction have always been played for laughs. He's taken down bears, elks, and (once, by accident) ate a vampire because it was in bat form. However, under normal circumstances, Vampires are extremely hard to kill. Everyone who knows anything about vampires knows that. In this book alone, it takes complete incineration (normal fire, holy water, phoenix flame,) otherwise nothing less than decapitation followed by other traditional methods (such as the classic stake through the heart.) However, Greebo was able to kill a vampyre with simple, offscreen savagery. What the hell did Greebo do to him? And if he could do that to a vampyre, what could he do to a human that pissed him off?
 * Greebo already killed a vampire once in Witches Abroad, though that was played for laughs.
 * Perhaps Greebo doesn't, in fact, 'know anything about vampires'. Being unaware that he can't kill the vampire, he just goes and does it, and the universe can't catch up in time to tell him that it is impossible.
 * Hilarious in Hindsight: Vlad mentions that he can't read Agnes' mind, thus taking a potentially romantic interest in her. Sound familiar?
 * The entire relationship comes off as scathing point-by-point parody of the one in Twilight, despite predating it by about a decade.
 * Well, Pratchett did once sarcastically reply to a Fan Dumb complaint that yes, he happened to own a time machine and had used it to steal the Unseen University concept from J.K. Rowling...
 * A Sarcastic Confession, perhaps?
 * It makes more sense if you consider that Twilight itself is basically a bad Fan Fiction of the Anne Rice kind of vampire, which certainly did exist at the time Carpe Jugulum was written.
