expensive gifts. Midge Pinciotti Portrayed by Tanya Roberts: Bob's wife and Donna's mother. Midge is the woman that Eric and his male friends fantasize about when coming of age. Although often dim-witted, she is also a kind-hearted woman who develops feminist ideals. She and Bob divorce when she is written out of the series after the third season. She later returns during the sixth and seventh seasons, in a recurring role where she and Bob almost reunite, but they then decide that they are better off apart. Laurie Forman Portrayed by Lisa Robin Kelly/Christina Moore: Eric's beautiful but mean and promiscuous older sister. She is also the foster sister of Steven Hyde. Laurie enjoys tormenting Eric and manipulating her father. She is often seen with various men, mainly Eric's friend Kelso (who cheats on his girlfriend Jackie). Eric, Hyde, and Donna often mock her promiscuity, including calling her "The Village Whore". Laurie has a strained relationship with her mother who, unlike her father, sees Laurie for what she really is. Laurie leaves the series during the third season but returns in a recurring role during the fifth, somewhat chastened. At one point, she genuinely seeks out a loving relationship (rather than merely physical) with Kelso, who is dumbfounded. She also becomes attached to a baby for whom she is babysitting and feels quasi-maternal pangs, which soon disappear. In season five, she and Fez marry to prevent him from getting deported. In season six she regresses to her previous self. Due to Kelly's health issues, Laurie was portrayed by Moore. Leo Chingkwake Portrayed by Tommy Chong: A hippie, and the owner of a Foto Hut at which Hyde once worked. Leo is an Army veteran who served in World War II, where he was awarded a Purple Heart. He would have had a promising medical career ahead of him after the war ended, but he became the stoner he is today after accepting a ride home with some musicians that were smoking marijuana. Leo often puts play before work and maintains an easy-going attitude in most things, business included. He disappears from the series after season four but is later referenced in season five's "The Battle of Evermore", when the gang goes on an unsuccessful mission to find him, finding only a letter from him explaining that he remembered he has a wife and should probably go back to her.
