Sing along...
(these, and the Gang Bang song, are courtesy of John Valby)
these were not necessarily sung in this order:
 
There once was a man from Nantucket,
Whose dick was so long he could suck it.
He said with a grin
As he wiped off his chin,
"If my ear were a cunt I would fuck it."
 
Ay, ay, ay, ay.
Your sister rides bicycles without seats.
Oh sing me another verse, worse than the other verse,
and toss me around by my willie.
 
There once was a priest from Morocco,
Whose motto was really quite macho.
He said, "To be blunt,
God decreed we eat cunt;
Why else would it look like a taco?"
 
Ay, ay, ay, ay,
Disco freaks suck mirror balls,
Oh sing me another verse, worse than the other verse,
and toss me around by my willie.
 
There once was a rabbi from Peru,
Who was vainly attempting to screw.
His wife said, "Oi, vay!
If you keep on this way,
The messiah will come before you."
 
Ay, ay, ay, ay,
Your mother's so dry the crabs carry canteens,
Oh sing me another verse, worse than the other verse,
and toss me around by my willie.
 
There once was a man from Cape Horn,
Who fucked till his dick was torn.
So he gave it a twist,
Instead of coming he pissed,
And that's how [n-keyers] were born.
 
Ay, ay, ay, ay,
Santa Claus has elf-cum on his boots,
Oh sing me another verse, worse than the other verse,
and toss me around by my willie.
 
There once was a young lady named Dot,
Who used to eat pig shit and snot.
When she couldn't get these,
She'd eat the green cheese,
That she scraped from the sides of her twat.
 
Ay, ay, ay, ay,
If you like that you're a sick motherfucker,
Oh sing me another verse, worse than the other verse,
and dance on my balls till I'm silly!
