How do the narrator, Rodrick, and Manny react when their dad, as he is picking out fishing poles, says they are going to live off the land?

The narrator and his brothers react very differently to their dad’s comment about living off the land. The narrator thinks that the only fish he will consider eating is in the shape of a stick. His brothers, on the other hand, Rodrick and Manny quickly end up in the hunting section, looking at hunting bows and big knives.
