If DOUG BENSON really smokes as much weed as he claims to, then the fact that he even wakes up in the morning is just as impressive as his long list of work-related accomplishments. Aside from creating, writing and starring in the theatrical hit, The Marijuana-Logues, Benson is also a regular contributor to VH1's ever-popular "Best Week Ever." He was also a Season Five finalist on NBC's "Last Comic Standing," though the censors limited the sarcastic, tongue-in-cheek glory of his actual material. Benson finishes a four-night run at the Funny Farm Sun., JAN. 13. $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.
