7. Beverly Hofstadter (Christine Baranksi)
"C'mon, I mean you're not upset that your marriage is over?" "Well, initially I did feel something akin to grief and perhaps anger. But that's the natural reaction of the limbic system to being betrayed by a loathsome son of a bitch.'" It was a battle of the parental units for a brief moment in time when deciding if Sheldon's mother was more a show-stealer than Leonard's. She's a psychiatrist fond of bringing her work home with her, meaning an unpleasant childhood for the emotionally stunted Leonard. Mary Cooper has had a lot more screen time than uptight, unaffectionate Beverly Hofstadter, but she steals spot number seven and the show based on one episode alone... where she makes out with Sheldon, and regrets it terribly while hungover in the back of the car with her son on the way to the airport. Nice one, Bev.
