"Little Boy Blue ... he needed da money!!!" So went ANDREW DICE CLAY's Brooklyn-accented, heavily scatological humor, which became a bizarre and unlikely hit in the late 1980s and early '90s. One wonders just how seriously the Diceman took the persona that helped him earn a No. 95 ranking on Comedy Central's "100 Greatest Stand-Ups of All Time." His Las Vegas show is near-legendary, and his recent VH1 reality show "Dice: Undisputed" traced his comeback attempts. Clay's appearance at the Punchline Tues.-Wed., JULY 3-4, should be, at the least, interesting. $100. 8 p.m. 280 Hilderbrand Drive. 404-252-5233. www.punchline.com.
