One Piece Chapter 18, page 9: Buggy, 'The Clown Pirate'

Buggy boasts that dodging his flying knives 'IS MOST LIKELY IMPOSSIBLE!!' Luffy retorts, 'WHY NOT?' and stretches his arm out to grab the edge of a nearby building roof with a 'STREEEETCH...' sound effect. With a quick 'PULL!', Luffy slingshots himself away, narrowly avoiding the knives that slash through the air behind him with a loud 'SWOOSH!!' sound effect.
