Trojans, they are a brand of contraceptive in the US, 'Johnny Bags' they used to be called in the UK. I've never used one and I don't intend to.

TROJAN

I worked like a Trojan
In the belly of the wooden horse,
Where's Helen?
I tapped the typewriter keys
To produce lighter and lighter
Verse, I wasn't messin'

Exhausted by the lyrical effort
A pale Chopin, I didn't
Have a cigarette or a mention
In Poet's Corner,
Or Mount Parnassus,
Not even the Scottish Poetry Library

I would never see
The ancient city of Troy
Or shake hands with Leonard Cohen
No master song in my poems
But I rushed that citadel at last
With amazing power
You mandarins! You gatekeepers!
What's another Trojan Horse
Attack in your land?
