This year, when people ask how you're going to spend your summer vacation, you might get to tell them you were locked in a house with about a dozen strangers, no privacy, and a live video feed of Julie Chen. CBS' Big Brother hosts an open casting call at Virginia College in North Charleston (6185 Rivers Ave.) on Fri. April 16 from 4-7 p.m. Applicants must bring a complete application (available at live5news.com), a photocopy of their driver's license or state-issued photo ID, a photocopy of their passport or Social Security card, and two photos (one of their face and another body shot). At the casting, you'll have help recording your audition tape, which can be no longer than two minutes. We'd give you some advice on what to do, but we don't want to give a head's up to our competition.
