<P> Midge was the neighborhood mom Eric Forman and his male friends fantasized about when coming of age (although Kelso and Fez have both admitted to having sexual feelings for Kitty Forman). During one episode when Kelso and Fez thought that Eric had sex with Midge due to Midge's panties being left behind after a Midge - Bob encounter in the Vista Cruiser, they immediately began bowing to Eric and calling him "a God! A God, I say!" She is also dim - witted, which often results in her being the butt of jokes . </P> <P> Problems arise when Midge starts expressing dissatisfaction with just being a housewife, which Bob, being a somewhat old fashioned kind of guy, had difficulty accepting . They begin to fight regularly and in the second season they separate, but continue to live in the same house under the agreement that they could see other people; something Red and Kitty felt was a bad idea and encourage Bob to "think hard" about it . At Red's birthday, Bob and Midge brought along separate dates, but Bob got annoyed with Midge's date . Bob's argument with Midge led to a passionate tryst in their car . Eventually Bob and Midge reconciled and renewed their vows . </P> <P> Tanya Roberts left the show in 2001, which led to Bob and Midge's divorce and the dimwitted Midge's departure for California to "pursue a career on Broadway", although Roberts returned as Midge for several episodes in later seasons . </P> <P> Bob has a strange obsession with the banjo . In one episode, he advises Eric to deal with a rival for Donna's affections by hitting him with a banjo, while in another, he advises Red to help Kitty get over her menopause by getting her a banjo . When a skeptical Red asks, "A banjo, Bob?" Bob answers that, "I can't hold a banjo and not smile ." Red sarcastically replies that "you can't hold a potato chip and not smile ." Bob then immediately proceeds to smile and agrees . </P>
