The Marines was a fresh start - that is why they shave your head. I wish they would let you change your name.

Carey jokes about the military’s ritual of stripping away individuality to create a new identity. The shaved head becomes a symbol of institutional “reset”—a visible, immediate break from civilian life and past habits. His punchline (“I wish they would let you change your name”) pushes the idea further: if the Marines are truly about transformation, why stop at appearance? The humor depends on exaggeration, but it also points to a real dynamic of boot camp—re-socialization through uniformity, discipline, and the temporary suspension of one’s prior self. The line balances admiration for reinvention with a comic skepticism about how complete that reinvention can be.
