Michael Christopher Kelso is a fictional character and one of the four 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, but unintelligent, male. He spends most of the series in an on-and-off relationship with Jackie Burkhart, whom he continues to obsess over following their breakups, a recurring plot-point in the series.
