Once dubbed one of six comics could replace David Letterman, the infamous Chuck Booms was best known for being the loudmouth on Sports Radio 92.3 before he got canned. The Cleveland native has appeared on national television more than 150 times and has had spots on the Today Show and Larry King Live. He brings his opinionated brand of sports talk and comedy to the Improv stage tonight at 7:30. Tickets are $17. (Niesel)
