One Piece Chapter 30, page 13-15: GREAT!!!

With a mighty roar of "AAARRGH!!!", Luffy rips the giant cat-head bow completely off the front of the pirate ship. The Black Cat Pirates cry out in terror, "WAAAH! HE'S TAKING OFF THE BOW! HE'S DESTROYING OUR SHIP!!" Jango is sweating profusely, while Nami cheers, "GO! LUFFY!" and Usopp looks on with his mouth hanging wide open.

Luffy turns around, holding the massive wooden ship bow over his head, preparing to throw it. The pirates panic, screaming, "HE'S TRYING TO KILL US!! CAPTAIN! HELP US!!" Realizing the danger, Jango quickly swings his pendulum again, shouting, "NO! WAIT! I'LL SAY '1, 2, JANGO', AND YOU WILL FALL ASLEEP! ONE... TWO... JANGO!!

The hypnosis works instantly on Luffy, who falls fast asleep with a loud "ZZZ...". However, because he fell asleep while holding the massive ship bow, he drops it. The giant wooden cat head crashes down with a colossal "DOSHUUU!" directly onto the crowd of Black Cat Pirates, crushing them beneath its weight. Only Luffy's legs stick out from underneath, snoring peacefully.
