Then: Dan Schneider played the wisecracking, trouble-making computer hacker Dennis Blunden in 'Head of the Class.' Fans of '80s movies will also remember Schneider for his role in 'Better Off Dead', in which he played John Cusak's dorky next-door neighbor Ricky Smith, who lived with his domineering mother and a cute foreign exchange student.

Now: Schneider began his writing career when he penned an episode of 'Head of the Class' as a 22-year-old. And, my, has it taken it off. The now 45-year-old is the writer and creative force behind 'What I Like About You,' Zoey 101' and 'iCarly,' among other shows. He's been so successful with kid-oriented programming that The New York Times referred to him as "the Norman Lear of children's television."
