A professional -- and always out -- standup comedian for going on 30 years, Kate Clinton never seems to have a shortage of jokes about her life and current politics. And right about now, gays and lesbians especially could use some laugh therapy. Friday, Nov. 12, at 7:30 p.m. The Birchmere, 3701 Mount Vernon Ave., Alexandria. Tickets are $45.
