That's the way to do it...

A Marxist response appears called for:

Groucho Marx: Hello, I must be going.
I cannot stay, I came to say
I must be going.
I'm glad I came, but just the same,
I must be going.

Margaret Dumont: For my sake, you must stay,
For if you go away,
You'll spoil this party I am throwing.

Groucho Marx: I'll stay a week or two,
I'll stay the summer through,
But I am telling you,
I must be going.

Chorus: Before you go, will you oblige us
And tell us of your deeds so glowing?

Groucho Marx: : I'll do anything you say,
In fact, I'll even stay,
But, I must be going.
