If They Do Go Either Way, They're Usually Fake (S01E07)

Charlie's beautiful friend Cindy (Kristin Dattilo) frequently showers at Charlie's house after surfing. When Jake sees a butterfly tattoo on Cindy's partially nude behind and later draws a picture of it in his classroom, Judith gets angry and goes to talk with Alan and Charlie about letting her son see half naked women. To Alan's surprise, Judith and Cindy become friends. When Cindy teaches Judith how to surf, Alan wrongly suspects that the two women are sexually involved and confronts his estranged wife, who does not appreciate his assumptions. Meanwhile, Alan and Judith are both upset when Charlie teaches Jake about distinguishing women's fake implants from real breasts. (Warner Bros. UK)
