High School Musical 3
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.
