It's a shame that more people don't know about TOM SIMMONS (right). Perhaps it's because the Atlanta native is a true road warrior, having spent the last decade traveling all over the world entertaining troops and performing in clubs and on Comedy Central. A thinking man's comic, Simmons covers everything from race relations to fatherhood in his stand-up. From Thurs.-Sun., DEC. 28-31, Simmons brings his thought-provoking and down-to-earth comedy to the Funny Farm (with a special "Year in Review" show on New Year's Eve). Regular tour: $10-$13.50. Thurs., 8:30 p.m.; Fri.-Sat., 8 and 10:30 p.m. New Year's Eve Show: $25-$45. 8 and 10:30 p.m. 608 Holcomb Bridge Road, Roswell. 770-817-4242. www.funnyfarmcomedyclub.com.
