Crawling

Over your window you think I'm confused

I'm waiting for the divergent wasp

To complete my current ruse

You use a plate-glass screen

To protect my chosen target

But there's an air-pellet hole

I can crawl through to you

I am the fly in the ointment

I can spread more disease than the fleas

Which nibble away at your window display

Yes I am the fly in the ointment

I shake you down to say please as you

Accept the next dose of disease
