When BIG KENNEY takes the stage, his foot-long dreadlocks and 6-foot-3-inch, 250-pound frame belies the comedian's gentle and articulate delivery; his rant on dealing with automated phone operators is especially hilarious. He's a member of the Blacktop Circus Improv Troupe, and a local comedy scene staple performing at the Funny Farm Thurs. and Sun., DEC. 6 and 9. $15. 8 p.m. 608 Holcomb Bridge Road, Roswell. 770-817-4242. www.funnyfarmcomedyclub.com.
