All of Me - S3.E21

Cybill puts her foot down when she's chosen as a model for a shoe campaign only to see a billboard with her face - on a younger, thinner woman's ""waif"" body. Cybill decides to defend women of all shapes and sizes by defacing a billboard that depicts her face with someone else's waif-like figure. Meanwhile, Maryann freaks when she discovers that her son, Justin, is two-timing Zoey, and Ira decides to give up caffeine, which creates some abnormal side effects.
