context: stubb tricks a french guy into getting rid of his dead whale (with the help of one of his own crewmen) by telling him the smell will make his crew sick, so he can get at the ambergris. so he's telling this guy like "i'm about to screw you out of your whale" and the man translating english to french turns it into "yeah you better get rid of that thing now he says it'll kill us". pretty funny
