Unemployment's up. The dollar's down. Even Ed McMahon can't catch a break. Who doesn't need a good laugh? Chris Rock is sure to oblige, but, like all great comedians, he'll make you think, too. He may even piss you off. One guarantee: You'll leave Ovens Auditorium with a renewed appreciation for stand-up. $45.50-$75.50. 8 p.m. Ovens Auditorium, 2700 E. Independence Blvd. 704-372-3600. www.livenation.com.
