Veteran comedian Kathleen Madigan has performed on "nearly every late night show ever made" during the course of her 25-year career. In 2014, she was nominated for an American Comedy Award for Best Concert Comic, and she's released four CDs and two DVDs during the course of her career as well. She's also starred in two HBO specials, three Comedy Central specials and four CMT Salute to the Troops specials with Ron White. Madigan doesn't resort to profanity in her routines. Rather, she uses observational humor (and a good deal of sarcasm) to get laughs. She performs tonight at 8 at the Ohio Theatre. Tickets are $10 to $39.50. (Niesel)
