CB played a drunk for several years on Cybil. I believe the character was MaryAnn. Cybill was the American version of Absolutely Fabulous and MaryAnn was the Patsy character. Patsy and Edwina were both dialed down quite a bit for Cybil and MaryAnn. Cybil had to to use her acting chops to play somebody ditzy but convincingly likable. The likable part was a lot of work.
