On TikTok, comedian Lucas Zelnick often posts videos of his smackdowns with his hecklers. They are accompanied by captions such as “Comedian vs. 4 preppy whites,” “Heckler loves OJ Simpson,” and “Jewish comedian vs. woman named Cookies.” These clips, which have received more than 26 million likes, have earned him more than 400,000 followers on TikTok and 215,000 on Instagram.

“You can go from not being able to sell tickets to rooms of people that want to see you just from your clips,” says the 28-year-old. But jokes don’t always land on social media.
