Hello Twainians!

My professor, Al Erdynast, of Antioch University Los Angeles has lost the
citation for a Twain quote he uses for a class on Picasso.

The quote is: "Men have breasts too, but they are considerably less
decorative."

Can someone give me a clue where I might find the source for this quote?

Thank you very much,
