White

Hawkeye thought a lot of things were funny. "Let me get this right, Moony. You work mostly at night? And you dress all in white? Har-dee-har har." Thought that was a riot. Told him I don't wear white to hide myself. I wear it so they'll see me coming. So they'll know who it is. 'Cause when they see the white, it doesn't matter how good a target I am. Their hands shake so bad, they couldn't hit the moon.
