Three more of America’s funniest stand-up comedians come to Mason City for a one-night haha-palooza. Pat McGann (The Late Show) returns with comics Keith Alberstadt (The Late Show and Last Comic Standing), and Andy Hendrickson (The Late Show with David Letterman) for an evening packed with punchlines, devilishly clever writing, and hair-trigger laughs. A ticket gets you a seat even though you will be rolling in the aisles.
