Harvard grad school alum and former Popular Mechanics copy editor Lisa Lampanelli was once just another not-so-pretty face covering 1980s hair-metal bands. But then she gave standup comedy a try, got into the insult biz and her career took off. Now it's hard to imagine a Comedy Central roast without her filthy verbal bouquets. Hear her uncensored this week at the Mahalia Jackson Theater (8 p.m. Sat.). Tickets $37.25.
