Actually, comedians get their humor from life experience, quite often. Jests at their lady friends usually derive from arguments and bad feelings that may or may not be resolved. You can say what you want about it, but the end result is that it's tasteless and I'm sure the wives/girlfriends do not appreciate all of the jokes at their expenses. Backroads is right: Whatever a person has said has to come from somewhere inside of them. They might have to play the audience, but they have made a conscious decision to say what they say and probably said it not just to make people laugh but because they are on the audience's side with it. I doubt the announcer is ready to go slaughter illegal aliens, but what he said was in extremely poor taste and he should have thought better.
