TV's Most Lovable Lunkheads

Michael Kelso (Ashton Kutcher), That '70s Show

Kelso was dropped on his head as a child, which is basically the story of his life. How else do you explain his penchant for pre-Jackass jackass behavior, like skiing off the top of moving cars and falling off the water tower, like, every episode? Luckily, when the chips were down, Kelso had a big heart and enough brains — he did score a 1030 on his SATs — to eventually do the right thing.
