We filmed the first eight episodes of CHEERS before the series aired. So studio audiences were unfamiliar with the characters. As a result, when we did "Normisms" they just died horrible silent deaths. Week after week. No one understood it was a running bit. We kept writing them though, staunchly believing when the series finally aired it would catch on.
And it did. We were so proud of ourselves... until we had to write new ones for the next 200 plus shows.
Here's a montage of "Normisms" from season one.
