The “Saturday Night Live” stage has seen some of the wildest moments in pop culture history.
Unfortunately, “SNL” hasn’t always met its goal.
In short, plenty ofawkward moments have aired on “Saturday Night Live.”

Some moments, though, have been beyond awkward.
They’ve been controversial, shocking, disrespectful, and downright atrocious.
Here’s why these 10 stars were banned from “Saturday Night Live.”

After a controversial performance in 1977, Costello was banned from the program.
“I just wanted them to remember us.
I didn’t really have anything against the show.

O’Connor then said, “Fight the real enemy,” via (YouTube).
The moment was instantly controversial, and Lorne Michaels was not pleased.
“Sinead I thought was sort of the wrong place for it, I thought her behavior was inappropriate.

Because it was difficult to do two comedy sketches after it,” Michaels told SPIN (viaYahoo!
She addressed the performance in her memoir saying, “Everyone wants a pop star, see?
But I am a protest singer.

I just had stuff to get off my chest.
I had no desire for fame,” per an excerpt inRolling Stone.
The comedian was known for pushing boundaries, and he even famously rejected the appellation.

“I am not a comic.
I have never told a joke.
The comedian’s promise is that he will go out there and make you laugh with him.

He brought to life interesting characters and made for TV moments that were unforgettable to viewers.
However, that all ended after a bizarre bit about women’s wrestling.
In the bit, Kaufman asked for women from the audience to come on stage and wrestle.

Ebersol and company honored the results, and Kaufman wasn’t allowed back.
Tragically, in 1984, Kaufman died from lung cancer.
All of that good will wasn’t enough to keep Chase from receiving a ban, though.

“I didn’t get it.
You’re too old?
We’d had many people older than me hosting.

What did he mean?
I’ve never understood what he meant.
Whatever the real reason is, it seems unlikely that Chase will host “SNL” ever again.

In 1994, a monologue becamethe real reason Martin Lawrence is banned from SNL.
“Some of you are not washing your a** properly … Lawrencesaid, including inappropriate gestures and getting even more graphic with his words.
The show has since released his monologue, but some of the more sensitive bits have been omitted.
If you or anyone you know has been a victim of sexual assault, help is available.

Not all guests have shown the “SNL” writers that same respect, though.
Apparently Blake didn’t like what Kroeger had written.
And he threw it and bounced it off Gary’s face,” Sheffield said.
“He just wasn’t funny, and he was very critical of the cast and the writing staff.
Seagal’s episode didn’t go over well, and he was banned from ever hosting again.
Two writers had particularly bad experiences with Berle.
And when speaking with Alan Zweibel, Berle exposed himself to the writer.
For very clear reasons, Berle was banned from returning to Studio 8H.
In fact, it’s just the opposite.
Politics has been a tentpole of the show since its inception.
“On whatever side, if there’s idiocy, we go after it.
The band members from Rage Against the Machine know this better than anyone.
At the time of writing, the band hasn’t been back since.
Justin Bieber was a musical guest before he hosted the show, as was Billie Eilish.
But things didn’t go so well.
As far as the audience could see, Zappa wasn’t funny.
Behind the scenes, Zappa was also difficult to work with.
I want to have pumpkins hanging on a Christmas tree, pumpkins that eat people’s faces.
Pull that together by Saturday.”
