Worms - not the German City - but ones that reside in the earth and don't like the rain much

Today I saw a little worm,
It made me squeek and made me squirm,
Yet off it went to burrow, into soily soil,
And I traversed to my mirror, to squeeze my bloody boil.

Today I saw a little worm,
I said, "hello my friend, I've some germs in my head".
Said the worm to me, "well go to bed",
So I pondered, and did, what the little worm said.

Today I saw a little worm,
"Please help me", whispered the worm to me,
"For the Blackbird's after me for its tea,
And I cannot cry and I cannot flee".

So,
I put the little worm inside my Head,
And the Blackbird skulked away.
I married that worm that very day,
And from that very very moment
There was nothing more we had to say,
The worm was here and here to stay.
