When I played a club in Salt Lake City, I complained to the crowd about the low turnout. It's always good to berate the people who paid to see you because you're upset about the people who didn't show up. It's called misplaced anger, and without it, I wouldn't have an act.
I even get tired performing standup, which is normally a low-impact exercise in futility but looks hard the way I do it. That's why I take a lot of breaks, often stopping in the middle of a joke to catch my breath, or blame the crowd for not laughing before the punchline.
