Other CP0 comes to check on him:
"There's blood everywhere! You're bleeding so much! What the hell happened?!"
*The Very, Very Strongest starts playing*
Mr Gogachad: "Nothing...nothing happened! Our mission, our duty is completed. Mugiwara is dead."
*He stands there stoically with his arms crossed*
Other CP0 guy: "That's impossible, he's alive right now, fighting Kaido again!"
Mr Gogochad: "FUCK! That's it I'm retiring!"
