Sesame Street's the Count (real name: Count von Count) is quite possibly the most mathematically proficient vampire that ever lived. Well, unlived. Undied? Oh, you know what we mean. Though, now that we think about it, the Count never seems to add or subtract numbers. He just counts them while laughing maniacally. In the 1970s, he used to stun people into a hypnotic trance with his counting. But television execs worried that his supernatural powers would frighten young children, so the friendly puppet hasn't used them in nearly 30 years. He doesn't bite anyone either. Actually, is this guy even a vampire ... ?
