(PARTY LIKE A PORN STAR) After two days of sold-out screenings—all of tonight's screenings are sold out, although if you hurry you might still be able to score tickets to the just-added show on Friday at 4 pm—amateur porn stars and the crowds who love them converge at Havana. The winner of the contest will be announced (prize includes $2,000 and a trip to Vegas). Plus, door prizes from Babeland and DJ Curtis spinning '70s porn music. (Havana, 1010 E Pike St, 323-2822, www.thestranger.com/hump for more info. 9 pm, free.)
