Michael Christopher Kelso is a fictional character and one of the five male leads on Fox Network's That '70s Show, portrayed by Ashton Kutcher. Described in the show as tall, lanky and long-haired, Kelso was considered a simple-minded person until he moved to Chicago in the eighth season. Throughout the show, Kelso is depicted as a stereotypical "himbo", or an attractive, masculine person who relies upon their attractive nature excessively. He spends most of the series in a mutually parasitic relationship with the similarly-depicted Jackie Burkhart, whom he continues to obsess over following their breakups, which are a recurring plot-point in the series. In spite of his purported stupidity, Kelso is shown on several occasions not to be immature, merely unmotivated, displaying startling intelligence unbecoming of his usual personality or hi-jinx occasionally. Near the end of the series, Kelso becomes one of the first characters to completely break away from adolescence and into adulthood when he impregnates a girl with whom he had a one-night stand. To his friends' surprise, Kelso took responsibility for the child, moving to Chicago to take a job to support and be near his newborn daughter. Character biography Kelso was first introduced in "That 70s Pilot" as Eric Forman's less intelligent, loudly obnoxious friend who is dating a preppy, younger student, Jackie Burkhart, whom he first met in 1968 playing "Fort." But later in the season, the couple goes through multiple breakups. Much to his friends' annoyance, he frequently claims to be breaking up with Jackie but does not go through with it, in hopes she'll 'put out' eventually (but instead, Jackie breaks up with him first). Because of her, he misses out on a Todd Rundgren concert, instead spending the evening making out in the back of the Vista Cruiser. As the series progresses, it is later revealed that Kelso cheats on his girlfriend (most notably with Pam Macy and Eric's sister Laurie). At one point, Jackie finds out and banned Kelso from coming to her ski trip, though Michael still attempts to find a way there. Kelso also unwittingly gets his friends into trouble after driving them around in an apparently stolen car. They were arrested, though Eric's connections with his father got them out of trouble. Eventually, Kelso loses his virginity to Jackie, though they go through a scare that she may be pregnant, which turns out to be a false alarm.
