Why English is sooo BAD ??

So my sister's finally finished her dissertation and has moved to Bangalore to work. Having been apart for a long time, we were catching up and one of those conversations took us back to good ol' Sacred Heart School in Jamshedpur. We suddenly remembered a poetry recitation competition she'd participated in as a little girl and actually penned down the entire poem after Google returned a zilch!! And so here goes:

Lil' Sister begins reciting: Why English is So BAD?

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 nest full of mice,
Yet 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 called pen?

The cow in the plural may be cows or kine,
But the plural of vow is vows, not vine.

I speak of my foot and show you my feet,
If I give you a boot, would a pair be called beet?

If one is a tooth, and a whole set are teeth,
Why shouldn't the plural of booth be called beeth?

If the singular is this and the plural is these,
Why shouldn't the plural of kiss be named kese?

Then one may be that, and three may be those,
Yet the plural of hat would never be hose;

We speak of a brother, and also of brethren,
But though we say mother, we never say methren.

The masculine pronouns are he, his and him,
But imagine the feminine she, shis, and shim!

So our English, I think, you all will agree,
Is the craziest language you ever did see.
