Jenni Hendriks's mom often complained she was "a real smart**s," so she decided to make a career out of it. She moved to Hollywood and worked her way from coffee-fetcher to writer for the television series How I Met Your Mother. She is also a cartoonist whose feminist-inspired works have been published in Ms. magazine. A film school graduate, she knows how to rack focus and wrangle a cable and can tell you what a best boy does.
