Sometimes you leave a movie humming the tunes; and sometimes you have to run… John Cusack blasting In Your Eyes on a boombox held high over his head.

Wayne and Garth bashing their heads to Bohemian Rhapsody.

Michael Madsen slicing a guys ear off to Stuck in the Middle with You.

Tom Cruise dancing in his underwear to Old Time Rock and Roll.

This, unfortunately, is not an article about moments like those.

Did they think ooze would pack them into the theatres?

Even the teenaged Ernie Reyes Jr, who completely ruinedRed Sonjaas a kid, is tolerable here.

And then it all comes screeching to a halt when it happens.

Go ninja, go!

Amazingly, no chanting of Its your birthday!

The nightmare is complete when the Turtles themselves start to do their own spontaneous synchronised dance to the song.

Go ninja, go!

Sample lyric:Have you ever seen a turtle get down?

Look, its the Village People singing the praises of milky beverages.

Do I really need to spell it out for you?

And coming up in the next verse, a really rockin recipe for lentil soup!

8: Pierce Brosnan, S.O.S.,Mamma Mia!

But, really, who cares about the plot?

Peppers Lonely Hearts Club Band(relax, Im getting to it) existed to recycle Beatles songs.

Vocally, he has a shorter range than a North Korean ballistic missile test.

The end result is sheer pain.

The film also features a relentlessly cheery, amateurishly produced theme song called Hooray for Santy Claus.

The lyrics are unnecessarily cloying (why say Santy Claus when Santa Claus fits the meter just as well?

And I pity any parent whose child came home from the cinema singing this.

I dont really have to explain whats wrong with these lyrics, do I?

There hasnt been aHowlingmovie since.

Ah, I see.

The writer-director huffing propane actually explains a lot.

It couldnt get any worse, could it?

Yes, the Steppenwolf song that was a hit in 1968.

Another thing to note: this movie is not a musical.

This is the only time in the film that characters break out into song.

Sample lyric:Really?

Yes, Neil Diamond in blackface.

Whats worse is theres no context for this scene at all.

Its Neil Diamonds skewed, twistedideaof what a black group would be singing in 1980.

Maybe the blackface was just there to distract from the terrible lyrics.

Unfortunately, that next man is a foul-mouthed cab driver played by Sylvester Stallone.

Yes, I realise the whole point ofRhinestoneis that Sly is supposed to be a terrible singer.

But at the end of the day, were still being forced to endure terrible singing.

Its the equivalent of saying, Hey, those bamboo shoots under your fingernails hurt, dont they?

Well, theyresupposedto hurt.

So its all good, right?

Like every other comedy Stallone ever made,Rhinestonewas a complete critical and financial bomb.

What could go wrong?

If you said everything, you win!

Picking a worst moment from this movie was perhaps my toughest choice in assembling this list.

And this is a movie where robots robots!

-sing Shes Leaving Home.

But its far worse than that.

Bang, bang, Steve Martin made sure this song was dead.

Sample lyric:I see no reason to get perfectly decent Lennon-McCartney lyrics involved in this.

The film finds Ms.

Manners on the occasion of her marriage to Sir Michael Barrington (a pre-Bond Timothy Dalton).

The hotel where they spend their honeymoon just happens to be the site of an international summit.

And all of this somehow brings about peace in our time.

Dom DeLuise:Sir Michael is one ofEnglands top secret agents!

Hes bigger than 007!West:I never got a chance to take his measurements!

Athlete:Im a pole-vaulter!West:Arent we all!

Excuse me while I shudder.

Horribly, Dalton kicks things off by speaking the lyrics (Love.

Love will keep us together.

Think of me, babe, whenever.

), and when he finally gets to actually singing, his voice is pretty much nonexistent.

Look in my heart and let love… keep us together!West:What-ev-uh!

Easily, the worst musical moment in movie history.

Second, the original lyrics to the song are Young and beautiful /Someday your looks will be gone.

Obviously, that had to change, because someday had already come and gone for Mae West.
