In the past 10 years, comic books have gone from sticky-fingered fun for geeks to super-hip mainstream entertainment. If you haven't jumped on this bandwagon yet, then today, Free Comic Book Day (freecomicbookday.com), is the day. You can pick up superhero samples absolutely free at Bargain Comics (19 E. Bijou St.) from 10:30 a.m. to 3 p.m., the East Library (5550 N. Union Blvd.) from 11 a.m. to 3 p.m., the Briargate Library (9475 Briar Village Point) from 1 to 3 or the Woodland Park Library (218 E. Midland Ave.) from noon to 3. Get one, or fail to achieve sweet dorkdom. — Rhiannon Conley
