Damn... I loved Usopp's speech in this chapter. Usopp usually does give a comeback to villians that laugh at or insult Luffy.
I still love Usopp's reply to Ms Merry Christmas waaaaaay back in Arabstra after she laughed at the idea of Luffy becoming Pirate King.
I have to admit, this moment made me think of Ace some, with how easy he was to anger when someone insulted his captain.
