One Piece Chapter 1, page 35: Romance Dawn

The bandit walks up to Shanks and points a pistol directly at his temple with a loud "KLIK". He laughs: "Didn't you hear him?! Don't come any closer......or I'll blow your head off! Ha ha ha ha ha!!" Shanks remains completely calm, his straw hat shadowing his eyes: "You're putting your life on the line by pointing that at me." The bandit is confused: "Huh?! What're you talking about?" Shanks explains: "I'm saying it's not safe to point guns." Suddenly, Lucky Roux steps up and shoots the bandit point-blank in the head with a massive "BOOM!".
