"Guffaws for a Cause" is a raucous night of stand-up comedy from four of Chicago's top comedians: Rick Young, Colleen Brennan, Chris Murray and Soli Santos. All four will do short sets followed by an intermission. The second half involves a provocative Q and A with the audience. See the Citadel's website (www.citadeltheatre.org) for more information and to order tickets ($25).
