Mrs. Murphy's Daughter

"Mrs. Murphy, where's your daughter?
We came over to have some fun."
"She's upstairs makin' water.
She'll be down when she is done."

I love to see Mary make water.
She can make such a beautiful stream.
She can pee for a mile and a quarter.
You can't see her ass for the steam.

Harry A. Taussig collected this in Berkeley, between 1958 and 1963.
The first verse turns up in "Songs of Raunch and Ill-Repute's version
of "The Winnepeg Whore" (p. 28).
