Onscreen Graduations That Make Us Want to Go Back to School

Before there was Glee, there was High School Musical. By the end of the third movie, the East High students are color-coordinated in a sweet EH pattern and Troy (Zac Efron) closes out the class's high school years with an emotional "Once a Wildcat, always a Wildcat." Then the kids form an even more impressive wildcat shape. For the record, my high school class was not that coordinated.
