Comedian Dave Dugan, for years a regular on the nationally syndicated Bob and Tom Show, once told The Republic that his kids use his stand-up act against him when he tries to discipline them. “Lighten up,” they have said. “I thought you were supposed to be a comedian.” He will perform at 7:30 p.m. April 20 at the Harlequin Theatre inside FairOaks Mall, 2380 25th St. in Columbus. Tickets are $15 and $20. Information: davedugan.brownpapertickets.com or 812-343-4597.
