Dewey Finn
In 2003's School of Rock, Dewey Finn is a unique slacker in that he is passionate, but only about making music. Other than that, he's very much content with sleeping through the day and remaining ignorant to the world around him. "Would you tell Picasso to sell his guitars?" he once remarked incredulously.
Ferris Bueller
The tagline of Ferris Bueller's Day Off is "One man's struggle to take it easy," which defines Ferris Bueller to a tee. Ferris will do anything to play hooky for a day; he even involes his best friend and his girlfriend. After a day full of shenanigans, his parents even suggest he takes another day off at the end of the film, none the wiser to his activities in their absence.
