Pollution
By Tom Lehrer, 1965
If you visit American city,
You will find it very pretty.
Just two things of which you must __________:
Don't drink the water and don't __________ the air!
Pollution, pollution!
We got smog and sewage and mud.
Turn on your tap
And get hot and cold __________ crud!
See the halibuts and the sturgeons
Being wiped out by detergeons.
__________ gotta swim and birds gotta fly,
But they don't last long if they try.
Pollution, pollution!
You can use the latest __________,
And then rinse your mouth
With industrial waste.
Just go out for a breath of air
And you'll be ready for Medicare.
The city streets are really quite a thrill
If the hoods don't get you, the __________ will.
Pollution, pollution!
Wear a gas mask and a veil.
Then you can breathe,
Long as you don't__________!
Lots of things there that you can drink,
But stay away from the kitchen sink!
The breakfast __________ that you throw into the Bay
They drink at lunch in San Jose.
So go to the city,
See the crazy __________ there.
Like lambs to the slaughter,
They're drinking the water
   And breathing [cough] the air!
