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. Tall, lanky and long-haired, Kelso had been accepted as the local idiot until he moved to Chicago for the eighth season. His behavior is very much in line with a stereotypical oversexed lunkhead or himbo who gets through life on his good looks. He spends most of the series in a mutually parasitic relationship with the equally vapid Jackie Burkhart, whom he continues to obsess over following their numerous breakups.
