Comedian Sara Schaefer, 35, could have lashed out when she got word last November that MTV would not renew “Nikki & Sara Live,” the late-night series she co-hosted with Nikki Glaser. Instead, she took to Tumblr and posted a poignant essay about one of her earliest comedic fails, a ill-conceived sketch about a German and a robot. “In both cases,” she wrote, “I dove headfirst into a world I barely understood, and I gave it my f—ing all.” This weekend, she’ll give her all during a free stand-up show at the Kennedy Center.

Odd Jobs

Before she went all-in as a comic, Schaefer worked as a financial analyst at a New York law firm, performing comedy on the side. In 2008, she got a job editing pop culture content on VH1’s Best Week Ever blog. The next year, she became head blogger for “Late Night With Jimmy Fallon,” where her work earned her a pair of Emmy awards. In 2011, she added to her résumé with a gig writing for “Who Wants to Be a Millionaire.”

Best Friends Forever

With “Nikki & Sara Live,” Schaefer and comedy partner Glaser gave tween culture a talk show, cracking jokes about pop stars and living out their dream of interviewing Justin Timberlake. The two were a natural pairing on TV, thanks to the rapport built on their hilarious, intimate (and currently on hiatus) podcast, “You Had to Be There,” which they record in Schaefer’s Brooklyn apartment.
