This one is pretty terrible.
That's right Homer: pave the ocean so you don't have to deal with the inconvenience of irregular topography! Dynamite the reefs to save you the indignity of potentially cutting yourself on a coral protrusion! Drug the fish, for they might someday bite you! You jerk.
Homer, by the way, is one of DC's "everyman" characters - along with Ollie, Lucky and Stan - who skipped from job to job as the thematic gag strips demanded it, and since they were the chumps who usually showed up in Aquaman's comics, they all got to be skin divers. Horrible, lazy skin divers.
