A Cupful of Poison

(Inspired by China's tainted milk reports)
A cupful of poison
Before you go to bed tonight
You'll sleep well, dearest
And ne'er see the morning light

A cupful of poison
I feed to my lover
He always likes a cup
After he's had his supper

A cupful of poison
I drink before I go to work
Spasm of pain, I groan
Worries in my mind begin to lurk

Tomorrow it's all over
We're all either dead or sick
There've been reports in the news
Apparently it was in the milk.
