We'll begin with box, and the plural is boxes,
But the plural of ox should be oxen, not oxes.
Then one fowl is goose, but two are called geese,
Yet the plural of moose should never be meese.
You may find a lone mouse or a whole lot of mice,
But the plural of house is houses, not hice.
If the plural of man is always called men,
Why shouldn't the plural of pan be pen?
...
So our English, I think you will agree,
Is the trickiest language you ever did see.
