The version my extended family used to sing was even worse:

If I had the wings of an angel,
And a prick as white as snow,
I'd climb to the top of a mountain,
And piss on the people below.

I love to see Nellie make water,
She pisses a beautiful stream;
She shoots it a mile and a quarter,
And you can't see her asshole for steam.

I would welcome contributions. My family learned this ditty from noted
ornathologist and sailor Dennis Puleston of Brookhaven, Long Island, back in the 1940's.
