FridgeLogic: How come neither Tommy or Jody figured out how to turn people into vampires in ''[[Literature/BloodsuckingFiends Bloodsucking Fiends: A Love Story]]''? Tommy practically saturated himself in vampire lore that explained how the whole "biting and giving blood" thing works, not to mention that the method in the book wasn't even a subversion.
* Even if they had come across that particular creation method... "OK Jody, here's what we're going to do: I'll drink some of your blood, and then you murder me. Let's see if this works!"
** You'd think that the author, being Creator/ChristopherMoore and all, would have at least {{lampshaded}} that if it was the case.
