Off the top of my head, it's gotta be 'My Humps' by the Black Eyed Peas.

Lyrics:
What you gon' do with all that junk?
All that junk inside your trunk?
I'ma get, get, get, get, you drunk,
Get you love drunk off my hump.
My hump, my hump, my hump, my hump, my hump, my hump
My hump, my hump my lovely little lumps. (Check it out)

I drive these scrubber crazy,
I do it on the daily,
They treat me really nicely,
They buy me all these ice-ys.
dolce & Gabbana,
Fendi and then Donna
Caring, they be sharin'
All their money got me wearin' fly
Brother I ain't askin,
They say they love my ass in
Seven Jeans, True Religion,
I say no, but they keep givin'
So I keep on takin'
And no I ain't TAKEN
We can keep on datin'
I keep on demonstrating.

My love, my love, my love, my love
You love my lady lumps,
My hump, my hump, my hump,
My humps they got you,
She's got me spending.
(Oh) Spendin' all your money on me and spending time on me.
She's got me spendin'.
(Oh) Spendin' all your money on me, on me, on me

What you gon' do with all that junk?
All that junk inside yo trunk?
I'ma get, get, get, get, you drunk,
Get you love drunk off my hump.
What u gon' do with all that ass?
All that ass inside them jeans?
I'm goin make, make, make, make you scream
Make you scream,scream.
Cos of my hump, my hump, my hump, my hump.
My hump, my hump my lovely lady lumps. (Check it out)

I met a girl down at the disco.
She said hey, hey, hey yea let's go.
I could be your baby, you can be my honey
Let's spend time not money.
And mix your milk wit my cocoa puff,
Milky, milky cocoa puff,
Mix your milk with my cocoa puff, milky, milky riiiiiiight.

They say I'm really sexy,
The boys they wanna sex me.
They always standin' next to me,
Always dancing next to me,
Tryin' a feel my hump, hump.
Lookin' at my lump, lump.
You can look but you can't touch it,
If you touch it I'ma start some drama,
You don't want no drama,
No, no drama, no, no, no, no drama
So don't pull on my hand boy,
You ain't my man, boy,
I'm just tryn'a dance boy,
And move my hump.

My hump, my hump, my hump, my hump,
My hump, my hump, my hump, my hump, my hump, my hump.
My lovely lady lumps (lumps)
My lovely lady lumps (lumps)
My lovely lady lumps (lumps)
In the back and in the front (lumps)
My lovin' got you,
She's got me spendin'.
(Oh) Spendin' all your money on me and spending time on me.
She's got me spendin'.
(Oh) Spendin' all your money on me, up on me, on me.

She's got me spendin'.

Of course, Alanis Morrisette did a nice send up of the song...

On a similar theme...

"Milkshake" by Kelis

[Repeat x2]
My milkshake brings all the boys to the yard,
And their like
It's better than yours,
Damn right it's better than yours,
I can teach you,
But I have to charge

I know you want it,
The thing that makes me,
What the guys go crazy for.
They lose their minds,
The way I wind,
I think its time

[Chorus x2]
La la-la la la,
Warm it up.
Lala-lalala,
The boys are waiting

My milkshake brings all the boys to the yard,
And their like
It's better than yours,
Damn right it's better than yours,
I can teach you,
But I have to charge

I can see youre on it,
You want me to teach thee
Techniques that freaks these boys,
It can't be bought,
Just know, thieves get caught,
Watch if your smart,

[Chorus x2]
La la-la la la,
Warm it up,
La la-la la la,
The boys are waiting,

My milkshake brings all the boys to the yard,
And their like
It's better than yours,
Damn right it's better than yours,
I can teach you,
But I have to charge

Oh, once you get involved,
Everyone will look this way-so,
You must maintain your charm,
Same time maintain your halo,
Just get the perfect blend,
Plus what you have within,
Then next his eyes are squint,
Then he's picked up your scent,

[Chorus x2]
Lala-lalala,
Warm it up,
Lala-lalala,
The boys are waiting,

My milkshake brings all the boys to the yard,
And their like
It's better than yours,
Damn right it's better than yours,
I can teach you,
But I have to charge

I'm pretty sure that this thread could go on and on and on!

Excellent choices - and thanks, Rob, for the Alanis Morissette sendup.

I would also like to nominate "Disco Duck", by Rick Dees.

First single I ever bought.

I nominate "Wear My Ring Around Your Neck" by Elvis Presley for giving us THIS deathless lyric:

"Won't you wear my ring
around your neck,
and show all the world
I'm yours, by heck!"

Sorry about that, Frank. Just my own personal taste, by heck.

"Brand New Key" - Melanie

"My Ding-A-Ling" - Chuck Berry

Everybody have fun tonight...Everybody Wang Chung tonight...

I nominate Run Joey Run by David Geddes, which I'm actually fond of.

Daddy please don't
It wasn't his fault
He means so much to me
Daddy please don't
We're gonna get married
Just you wait and see

The stupidest Top 40 hit ever is "Disco Lucy" by Wilton Place Street Band.

A discofied cover of the I Love Lucy theme. "Dance, dance, disco Lucy" are about the extent of the lyrics.

Sadly, I've never been able to find it on CD.

Arlo Guthrie claims it's his song, "Motorcycle (Significance Of The Pickle)."

I don't want a Pickle
Just wanna ride on my motorsickle
Don't want a tickle
Just wanna ride on my motorsickle
And I don't wanna die
Just wanna ride on my motorcy.....cle.

I concur with Jimbo's unstated suggestion that stupid has never been a reason not to buy something and more often than not, it can actually encourage said purchase. How sad am I?

Rock Lobster - B 52's

We were at a party
His ear lobe fell in the deep
Someone reached in and grabbed it
It was a rock lobster

We were at the beach
Everybody had matching towels
Somebody went under a dock
And there they saw a rock
It wasn't a rock
It was a rock lobster

Motion in the ocean
His air hose broke
Lots of trouble
Lots of bubble
He was in a jam
S'in a giant clam

Down, down

Underneath the waves
Mermaids wavin'
Wavin' to mermen
Wavin' sea fans
Sea horses sailin'
Dolphins wailin'

Red snappers snappin'
Clam shells clappin'
Muscles flexin'
Flippers flippin'

Down, down

Let's rock!

Boy's in bikinis
Girls in surfboards
Everybody's rockin'
Everybody's fruggin'

Twistin' 'round the fire
Havin' fun
Bakin' potatoes
Bakin' in the sun

Put on your noseguard
Put on the lifeguard
Pass the tanning butter

Here comes a stingray
There goes a manta-ray
In walked a jelly fish
There goes a dogfish
Chased by a catfish
In flew a sea robin
Watch out for that piranha
There goes a narwhale
HERE COMES A BIKINI WHALE!

Hey, how about "Torn Between Two Lovers" by Mary MacGregor. If ever there was a song that could make me leap for the buttons on the car radio, this was it.

Hmmm....

"Torn Between Two Lovers" vs Debby Boone's "You Light Up My Life"

Talk about a real knock down, drag out crapfest!

This thread is actually making me nauseous. I'm not sure I want to remember the bad stuff -- and there's so much bad stuff to remember.

Like "Goin' Up the Country" by Canned Heat. I thought it was a joke the first time I heard it.

Anybody got any Maalox?

"I've been to Nice and the isle of Greece," not to mention the "That's truth, that's love" bridge... Nothing compares to "I've Never Been to Me" by Charlene.

Always hated it until it showed up in "The Adventures of Priscilla, Queen of the Desert," and now I smile every time I hear it.

I was going to mention "I've Never Been To Me" but than I remembered this gem:

"Fighting soldiers
from the sky
Fearless men
who jump and die

Men who mean
just what they say
Those brave men
of the Green Berets."

Something about men who were not afraid to simply jump and die always struck me as rather stupid, even at a young age.I mean, did they all just jump and die? Was there a point to this jumping and dying?

Geddes also wrote "Last Game of the Season (A Blind Man In The Bleachers)

And when the game was over
The coach asked him to tell
What was it he was thinkin' of
That made him play so well
"You knew my dad was blind," he said
"Tonight he passed away"
"It's the first time that my father's seen me play

I'm painfully aware of that. It was the b-side of the 45.

No worries, Jeff! It IS a pretty stupid song, but my 13 year old self thought it was incredibly funny! I must not have been alone in liking it - it went to #1 on the Billboard Hot 100!!!!!

Disco Duck by Rick Dees. That was stupid.
