Lately the storied House of Humor costume shop has had a run on fangs. With the popularity of True Blood and Twilight, vampires are cool again, and this is the place to get your bite on. At its current location for the last decade, House of Humor was in Mountain View for 25 years before that. They've lasted because of the quality of their costumes, wigs, makeup, accessories, etc. They've also got a big magic section, decidedly non-Hallmark cards, and an adult section, in case your favorite part of True Blood is the kinky vampire sex.
