Maybe it ' s a flashback sequence , Kill Bob can still see the Charlies in the jungle as they castrate and rape sad bunny . He couldn ' t do anything but watch , because he knew the same fate would befall him if he tried to interfere . He can still hear the pained screams , the blood and feces gushing from Sad Bunny ' s abdominal cavity , and his entrails filled with seed and strewn about the jungle floor . He can still smell the napalm scorching and engulfing the jungle in which Sad Bunny was ravaged . He hasn ' t been the same since , even after returning home . If he hears the gas stove click he is reminded of the napalm . When he turns the shower on he can hear the blood splattering upon the earthen ground . When his teapot whistles he can hear Sad Bunny ' s painful shrieks . He is a shell of a man , and his experiences in ' Nam have changed him for the worse .
