JIM NORTON (right) is like that friend you hesitate to bring around others because you never know who he will offend, you just know that someone's getting offended. His comedy follows in a similar vein -- foul, demented and rude -- but it's also honest, original and hilarious. Anyone looking for a fresh breath of dirty air can catch Norton -- who starred in his own HBO comedy special as well as HBO's hit show "Lucky Louie" -- at the Punchline NOV. 2-4. Bring an open mind and thick skin. $17.50-$19.50. Thurs., 7:30 p.m.; Fri., 8 and 10 p.m.; Sat., 7, 9 and 11 p.m. 280 Hilderbrand Drive. 404-252-5233. www.punchline.com.
