Very stupid and juvenile, but I replace “rock” with “cock” in I Wanna Rock by Twisted Sister:
I want some cock! (COCK!)
I WANT, SOME, cock! (COCK!)
I want some cock! (COCK!)
I WANT, SOME, cock! (COCK!)
I found myself singing another one here recently while doing the dishes. Derived from the Cookie Monster song “C is for cookie”
Z is for zombie, that’s good enough for me,
Z is for zombie, that’s good enough for me,
Z is for zombie, that’s good enough for me,
Oh, zombie zombie zombie starts with Z!
Nighttime would find me in Rosa’s vagina…
I’ve sung this since the 90’s, when a local group performed it.
Come and listen to my story "bout a man named Fred
A bold minister with lots of hate inside his head.
And then one day he was lookin’ for a cause
And said to himself “I’ll hate homosexuals!”
Queers that is, sodomites.
Well the next think you know ol’ Freds a picketeer
Cursing anyone he thinks remotely queer
We think that somewhere else is where he really outta be
And while he’s at it he can take his whole darn family
Siberia, Timbuktu
Well now it’s time to say goodbye to Fred and all his kin
We’re sorry but we can’t say that we’re glad that they stopped in
And if by chance they should come back to this locality
We;ll have to show them some of our great hospitality.
Tar that is, feathers
Don’t come back now, ya hear?
And SNL’s first verse:
Listen to the story about a man named Abdul
Poor Bedouin trying to keep his family full
Then one day he was shooting at some Jews
Up from the ground comes a bubbling ooze
Saudi soda
Persian Perrier
Nicely done!
While I don’t sing it outloud like this, for obvious reasons, every time I hear that song by 1910 Fruitgum Company Yummy Yummy Yummy I hear it as:
Yummy Yummy Yummy
I got cum in my tummy
I’m not entirely convinced the songwriters didn’t intend that anyway.
Metallica:
Sleep with one eye open
Gripping your weiner tight
Exit Light
Enter Night
Shake that hand…
You’re off to masturbation land!
Dean Martin - Sway
Other dancers may pee on the floor
Dear, but my eyes will see only you
Only you have that magic technique
When we sway, I go weeeeee!
Like a rhinestone cowboy cowpie
A college friend reworded Culture Club’s song
I’m a man without conviction
I’m a man without a penis
and
cum a cum a cum cumeleon
Back in the 70s when the whole horrid truth about John Wayne Gacy was discovered, that became an easy sub for “baby.”
Gacy, Gacy don’t get hooked on me
Be my, be my little Gacy
Gacy come back
Etc.
IIRC the radio station had revamped Pink Floyd’s “The Wall” as,
Hey, Gacy, leave those kids alone
All in all it’s just another kid in the crawl
Uh-woo-ooo-woo, driver’s seat dramedy.
As a wee-un, would sub “you” for “glue”:
Luh-uh-vin gluuuue, is easy cuz it’s beautiful.
those 1/12 scale Revel dragsters and funny cars, and those goddamn red and white tubes 
, eventually replaced by those wierd black and yellow tubes with the cray lemony scent 
I always sang the second verse of Bloody well right by Supertramp as
“Write your problems down on a tea-towel…”
(instead of “Write your problems down in detail”)
Just today Elton John was on the radio and I kept singing the song in my head as “Philadelphia Cream Cheese.”
1/16. Nice kits.
I’m not sure about “insist”, but we had our own version:
We don’t sex education
We don’t need no birth control
No fake orgasms in the classroom
Hey teacher-leave us kids alone
All in all you’re just
Another prick in the hall
My version is:
Even though I ain’t got honey
I’m so in love with my money
Today I was reminded of my Flashdance lyrics
Take you pants off and make it happen
Billy Idol: If I had the chance, I’d ask the world to dance I’d take off the world’s pants…
Was reminded of this thread the other day when Barbara Streisand came on the radio and I found myself singing along:
People
People who eat people
Are the HUNGRIEST people
In the world.…
Take one person
One very tasty person
Load him deep in your bowl
Then you were starved
{cheerfully} Now you’re full!
No more hunger or thirst,
But first,
Be a person who eats people.
Don’t have a cannibalism themed version for the verse about acting like children.
California, here I come
Right back where I started from
I wish I had some chewing gum
California, here I come!
…I’m so in love with ya money
Makes it more mercenary.
And for anybody in a Christmas mood.
Madonna has a song, “Erotica”, which contains the line,
“Erotic! Erotic! Put your hands all over my body!”
In Living Color did a parody, “Neurotica”, Which contains the line,
“Neurotic! Neurotic! A gay man trapped in a woman’s body!”
