JARROD HARRIS is one of Atlanta's true native comedic gems. Rising from the local open mics to headline clubs and colleges nationwide, Harris has taken his unusual brand of brainy, trailer-inspired humor and gained quite an underground following. His material is equal parts original and authentic. Comically and metaphorically speaking, Harris has taken the piss left in a bottle in his trailer and turned it into lemonade. $12-$20. Thurs., 8 p.m.; Fri.-Sat., 8 and 10 p.m.; Sun., 7 and 9 p.m. Laughing Skull Lounge, 878 Peachtree St. 877-523-3288. www.vortexcomedy.com.
