Tom Lehrer - She's my girl

Sharks gotta swim, and bats gotta fly,
I gotta love one woman till I die.
To Ed or Dick or Bob
She may be just a slob,
But to me, well,
She's my girl.

In winter the bedroom is one large ice cube,
And she squeezes the toothpaste from the middle of the tube.
Her hairs in the sink
Have driven me to drink,
But she's my girl, she's my girl, she's my girl,
And I love her.

The girl that I lament for,
The girl my money's spent for,
The girl my back is bent for,
The girl I owe the rent for,
The girl I gave up lent for
Is the girl that heaven meant for me.

So though for breakfast she makes coffee that tastes like shampoo,
I come home for dinner and get peanut butter stew,
Or if I'm in luck,
It's broiled hockey puck,
But, oh well, what the hell,
She's my girl,
And I love her
