If you can say something to people that's maybe a little bit insulting, but they're kind of giggling as they are hearing it, if you say something to their face without them getting mad at you, I think that's the right balance. You don't want to make it uncomfortable, especially for the viewer or the people around either. Sometimes that happens. You're watching and you're like, 'Uh, this is awkward. I don't want to look!' But, if everybody's enjoying it, I think that works.
