Pour your shots, tap your kegs and get ready to laugh and/or cry, because comedian DAVE ATTELL is coming to town. Stand-up's most notorious angry drunk does realistic shock comedy better than anyone, drawing hilarity from topics like murder, alcoholism and sexual failures. With his sad-clown act delivered through the pack-a-day rasp that is his voice, Attell makes light of the dark side of life like nobody's business. He performs at the Punchline for three nights. $35. Fri., 8 and 10 p.m.; Sat., 7, 9 and 11 p.m.; Sun., 8 p.m. 280 Hilderbrand Drive. 404-252-5233. www.punchline.com.
