Appearing on 'SNL' can be career-altering, however, at the same time, it can also cause a lot of stress for the actor or actress involved. Take Billie Eilish as an example, when she hosted the show, the A-list singer was insanely nervous during the buildup.

The same can hold true in terms of performance, Adrien Brody was called "cocky and unfunny" by Tina Fey. The award-winning actor had a tough performance and is remembered among one of the worst.

The situation that we'll look at today, falls more so under the category of awkward, as this popular rapper decided to go completely off-script, in what Kenan Thompson called "extremely uncomfortable."

There Were More Than A Few Awkward SNL Hosts In The Past

Yes, we all love seeing our favorite celebs take the stage on 'SNL'. However, things behind the scenes aren't always necessarily smooth, and that even includes some of the top celebs in the world.

Bill Hader called Justin Bieber one of the worst behaved celebs he'd ever seen, claiming the singer looked completely out of it and tired during the time of his appearance on the show.

Donald Trump was also a nightmare to work with in the writers' room, very close-minded to most of the ideas that were thrown his way. Seth Meyers called the former President, lacking a sense of humor during his time on the show.

Among other tough hosts according to Tina Fey, including Paula Abdul and Paris Hilton. Fey had especially some choice words for Hilton, who really wasn't open to much while maintaining a large ego throughout her time behind the scenes on the show.

As it turns out, Kanye West can also be labeled under this field, as during his time on the program, the artist decided to go off-script, making things very weird for the cast, crew, and audience.

Kanye West Went Off-Script During His 'SNL' Guest-Appearance

It started off innocently but soon enough, it was obvious that Kanye West had his own agenda, going away from the comedy of 'SNL' and speaking out politically.

At the time, his rant was in regards to Donald Trump, "So many times I talk to a white person and [they] say, ‘How could you like Trump, he’s racist?’ Well, if I was concerned about racism I would’ve moved out of America a long time ago.”

“You wanna see the sunken place? Okay, Im’a listen to y’all now. I’ma put my superman cape on, because this means you can’t tell me what to do… You want the world to move forward? Try love.”

The tone of the room went from happy to completely silent... Kanye West's speech was ultimately unaired, though it made headlines everywhere, and it is believed that Lorne Michaels was none too pleased about it all. So much so that Kanye might be banned from the show permanently.

Not only was the moment hard for the viewers at home, who were watching with the intent of being entertained through laughter, it was also hard for those working on 'SNL'. That included a veteran of the show who wisely refused to go on stage during Kanye's rant.

Kanye West called everyone onto the stage before his rant... this made everything that much harder to watch. Given that he's a veteran of the game, Kenan Thompson was wise enough to head to the back instead.

He discussed the situation on Seth Meyers' Late Night Show', calling the moment awkward and uncomfortable.

According to Kenan, there was a time and a place for the moment, and that place was not 'SNL'. It caused the room to completely drop while putting his fellow castmates in a tough spot.

Nonetheless, fans still had fun with the moment, especially given the casts' reaction during the speech. One fan pointed out everyone's hilarious reaction, which was evident in the background of the rapper's speech.

"Alex: keeps teetering on his feet like he's waiting for the signal to take final bows and get the hell out of there. Mikey: confused as hell, pinching his lip like he wants to ask what the hell is going on. Colin: trying not to die laughing. He's not sure what bizarre world he's in either but things are definitely happening right now. Pete: he really said 'man, f this' and left."

A memorable moment and one the 'SNL' cast likely tried to forget about ASAP.
