After winning Season Two of NBC's "Last Comic Standing," JOHN HEFFRON became one of the circuit's most sought-after headliners. As his life has evolved from college slob to husband and father, so has his material, trading jokes about the ill effects of drinking for routines about frequent visits to the doctor and Home Depot. Heffron brings his laid-back routine to the Funny Farm for four nights, starting Thurs., Dec. 13, and closing out Sun., DEC. 16. $15-$20. Thurs., 8:30 p.m.; Fri.-Sat., 8 and 10:30 p.m.; Sun., 8 p.m. 608 Holcomb Bridge Road, Roswell. 770-817-4242. www.funnyfarmcomedyclub.com.
