Simpsons Comics #134

Homer saves the day and his friends during a work-related cruise by proving to be "unsinkable." Then, Mr. Burns looking for a way to assure the public that the Springfield Channel - his personal nuclear waste dumping site - is perfectly safe, he tricks Homer into swimming the channel as a publicity stunt. But what’s a dip in the water without a little childhood trauma and a killer whale out to settle an old score?
