'Whatever It Is, I'm Against It'

I'M AGAINST IT
By Bert Kalmar and Harry Ruby

[Groucho Marx]
I don't know what they have to say,
It makes no difference anyway,
Whatever it is, I'm against it.
No matter what it is or who commenced it,
I'm against it.

Your proposition may be good,
But let's have one thing understood,
Whatever it is, I'm against it.
And even when you've changed it or condensed it,
I'm against it.

I'm opposed to it,
On general principle, I'm opposed to it.

[Chorus]
He's opposed to it.
In fact, indeed, that he's opposed to it!

[Groucho]
For months before my son was born,
I used to yell from night to morn,
Whatever it is, I'm against it.
And I've kept yelling since I first commenced it,
I'm against it!
