Ha!
My uncle used to sing it:

In the shade of the old apple tree
Is where she first showed it to me
It was smelly and brown
with hair all around
But it looked like a bird's nest to me

So I took out my Pride of New York
It fitted her just like a cork
She giggled, "Tee hee,
Take it out while I pee..."
In the shade of the old apple tree.

followed by

Walkin' down Main Street, lookin' in ev'ry door
I'll be a sonofabitch if I could find a whore..."

There's more but that's enough of that one.

There were a few others:

Two Dutchmen
Brown, Brown, Dirty Old Brown (The Ballad of Officer Reilly)
The Ring Dang Doo
Stompin' Tom's version of Green Green Grass of Home

Then my cousin and I would throw a few MacLean & MacLean ones into the mix:

The Fox and Fuck Ya and:

All day, all night, Mary-Ann
All day, all night, Mary-Ann
All day, all night, Mary-Ann
What the hell do you think I am, Superman?
