october 16 Gilda's Club The late, lamented comedienne Gilda Radner once said that having cancer gave her membership into an elite club to which she'd rather not belong. The legacy she left is a clubhouse for other people who'd rather not belong. Gilda's Club, in New York, offers cancer patients a cozy place for support and understanding, and funds are being raised to open other Gilda's Club clubhouses throughout the country. Tonight, Laff Stop, ComedySportz and special guests present a silly benefit for a sober cause. 8 p.m. The event will be at the Laff Stop, 1952 West Gray. For information or reservations, call ComedySportz, 521-2226. $10.
