What do rich people want to do when they retire? Live by the ocean and fish. Octopus are already doing it.
The current champion in the Battle of Troublesome Pluralization is octopus, which, depending on which dictionary is consulted, may be written in three different ways: octopi, octopuses, and octopodes. Such a range of options might prompt even the most patient learner of the language to say “what the hell? C’mon, English, get your act together.” This state of affairs is not so much the fault of the English language as it is of the people who speak it, who have been debating the proper way to pluralize octopus for a very long time.
