her "whisker face." Kelso's father, John Kelso, appeared in the episode Career Day, portrayed by Francis Guinan. John Kelso's office job as a "Senior Executive Statistical Analysis Technician" is unclear and confusing to Michael, who decides to make it up and say his dad is a farmer. Reception Kelso is considered by many fans as the breakout character of the series. In the earlier seasons he was a supporting main character but in seasons 6-7 he becomes one of the shows leads along with Eric, Donna and Hyde. Kelso was also described by TV Guide's as one of 'TVs Most Lovable Lunkheads.' Other appearances Kelso was portrayed once again by Ashton Kutcher in a Robot Chicken sketch entitled "That '00s Show". Critics have noted striking similarities to the portrayal of Kutcher's character Walden Schmidt on Two and a Half Men to that of Kelso. Walden's personality, however, drastically changed since his initial appearances and by the series' end he was a completely changed man. Other similarities drawn are between that of his role as Jesse Montgomery III in the stoner film Dude, Where's My Car? (2000).
