(Spaulding/Groucho)
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.
La La.

(Mrs. Rittenhouse/Margaret Dumont)
For my sake you must stay.
If you should go away,
You'd spoil this party I am throwing.

(Spaulding/Groucho)
I'll stay a week or two,
I'll stay the summer through,
But I am telling you,
I must be going.
