Troy Bolton: East High is a place where teachers encouraged us to break the status quo and define ourselves as we choose. Where a jock can cook up a mean crème brulee, and a brainiac can break it down on the dance floor. It's a place where one person, if it's the right person, changes us all. East High is having friends we'll keep for the rest of our lives, and that means we really are 'all in this together'. Once a Wildcat, always a Wildcat!
At Riley's Garage, when Troy and Chad are about to rummage through the junk looking for the radiator cap, Troy raises his arms and his boxers are light grey, but next shot when he lifts the truck's hood his boxers are black. It's also noteworthy to mention that during "Boys Are Back," young Troy is wearing patterned boxers, though all other clothing is identical.
