First time i watch a stand-up comedy with Steve Byrne and overall it was a good experience. He clearly has a funny bone and can bring his jokes like a natural born comedian. I do get though that some people are a bit offended by his material, because let's just be honest, sometimes it is a bit offensive. There is alot of stereotyping so people could be offended by that, but I see it as humor and not as deliberately attacking a certain group of people. I'll admit he flirts with "borderline" jokes but I think you should be able to laugh with everything as long as you're not targeting one specific person and try to hurt him/her deliberately. Steve Byrne's show Champion will probably not be to everyone's taste but for me it worked.
