Drop the big one

I heard this song on the radio today by Randy Newman called Political Science and was amused by how it is so apropos of the world today.

No one likes us
I don't know why.
We may not be perfect
But heaven knows we try.
But all around even our old friends put us down.
Let's drop the big one and see what happens.

We give them money
But are they grateful?
No they're spiteful
And they're hateful.
They don't respect us so let's surprise them;
We'll drop the big one and pulverize them.

The song was familiar but I couldn't place it in time so I looked it up. Randy wrote this bizarre little gem in 1968. Interesting.
