GARY GULMAN has worked his way up the stand-up comic ladder. Garnering breakthrough success on NBC's "Last Comic Standing," Gulman mastered the late-night talk-show circuit, starred in his own special, "Boyish Man," and toured with comedian Dane Cook. Gulman's witty, passionate rant against sugar cookies' blandness, grapefruit's suckiness and Pepsi's arrogance earns him a spot at the Laughing Skull Lounge. $15-$23. Thurs., 8 p.m.; Fri.-Sat., 8 and 10 p.m.; Sun., 7 and 9 p.m. 878 Peachtree St. 877-523-3288. www.vortexcomedy.com.
