Nerds! Seattle's largest comic-book convention is here, and for the ninth straight year, it's grown in size and scope. For three days this weekend, you'll be attending panels (Brent Spiner! Webcomics! "Anthropology of Star Wars"!), meeting your favorite actors (BRENT SPINER!) and comics artists, and hunting for the funny-book bargains of your dreams. It's Geek Christmas in Seattle, and Santa looks a hell of a lot like William Shatner. Come to complete your Power Man and Iron Fist collection, and stick around for some of the best people-watching imaginable. (Washington State Convention Center, 800 Convention Pl, www.emeraldcity comicon.com, 10 am–7 pm, $25 one-day pass)
