In _Slaughterhouse Five_, Kurt Vonnegut quotes one verse of a very filthy song:

In my prison cell I sit with my britches full of shit,
And my balls are flopping naked on the floor,
And I see the bloody snag where she bit me in the bag,
Oh, I'll never fuck a Polak any more!

I've never heard this one sung, but it seems this verse would fit well to the The Rambles of Spring, or possibly Tramp, Tramp, Tramp Our Boys Are Marching.

Does anyone know the rest of the lyrics to this song? The preferred tune? The title? Anything?
