This is going to sound stupid but here is the question: Why does Adolf Hitler have a perfect mustache?

Hitler actually had a larger mustache but his superiors (back when he had them) ordered him to clip it short for his gas mask to fit. He trimmed it regularly because he regularly needed his gas mask.

Explanation:

Adolf Hitler al principio quería un bigote bávaro * del tipo que se puede colgar un sombrero * Pero sus superiours le dijeron que lo cortara un poco.
