10. Cameron Would Never Have Rebelled Against Daddy
The Movie: Ferris Bueller's Day Off Where would we have been if neither Ferris, Cameron, nor Sloane (nor those professionals at the parking garage) knew how to drive Cameron's dad's prized car? Sure, Ferris could have chosen another car, but the resolution of the movie's journey could have ended much differently, not to mention much less chic. Without that particular car, the very meaning behind the teens' adventure would have missed its mark, and none of them would have been able to as profoundly appreciate the grandeur of what it really means to look around once in a while.
