look What are the Slits in These Sunglasses For? We took this strange pair of 1960s Pierre Cardin sunglasses to Blue In Green (7 N. Third St.) and asked the patrons and staff to suggest the raison d'être of the slits. We also took them backstage to a Cheap Trick concert in Baltimore to ask guitarist Rick Nielsen. Here's what they had to say. "They function not unlike an exotic dancer's g-string?" -Anahi Baca, java slinger/waitress "They're for business cards!" -Will Augerbraun, customer "They're so stoners can use Visene without having to take their sunglasses off." -Ben Avery, waiter "They're air-cooled like Ben's Volkswagen bus." -Bruce Reckahn, cook/bassist for Delta 72 "They're for butterfly kisses." -Rick Nielsen, High Priest of Rhythmic Noise/guitarist for Cheap Trick Note: Rick refused to wear the Pierre Cardins, claiming that they were "too fruity," and is instead modeling some shades from his collection (which, allegedly, rivals Elton John's).
