The NBC comedy Cheers was all about feeling good. Fans don’t associate it with horror. But, for writer Ken Levine, working on Cheers had some scary moments. Levine, with his partner David Isaacs, wrote 40 episodes of Cheers. They were responsible for a “Monster” Norm (George Wendt) joke and integral to the transition from Shelley Long to Kirstie Alley, but those weren’t the scariest times.

Levine revealed his scariest moment on Cheers on an episode of his Hollywood & Levine podcast. If you’re a writer, grab your blankie and night light because Levine’s fear is palpable.
