I performed standup comedy for 10 years and never once got slapped. I got booed, heckled and glared at. The most hurtful times were simply being ignored. That happened a lot in sports bars on dollar beer night with no cover charge.
It wasn’t all bad. I made a little extra money on weekends and somehow won the Utah Laugh Off twice blissfully back at the tail end of the 1980s. It was a somewhat pyrrhic prize. None of the major night clubs or talk shows ever called to book me for my Utah award.
