Heroes Off Duty hands the microphone to first responders and veterans who have turned life on the job into stand-up comedy. At Houston Improv, the touring showcase draws on the experiences of police officers, firefighters, medical workers and former military personnel, with stories that put a funny spin on demanding work. It is a fitting group outing for people who recognize the shift-work chaos firsthand. The show is 18+ and ticketed; a two-item food or beverage minimum applies in the club.
