"So, did you stab Edward Cullen with a pencil or what?"

Legend has it that one of the only ways to kill a vampire is to stab it through the heart with a wooden stake. The preferred wood was ash, hawthorne or oak. However this method would not work on Stephenie Meyer's Vampires:

Q&A with Stephenie Meyer (from the twilight lexicon)
