Colin Jost defied the NBC censors on "Weekend Update" in the first "SNL" episode after the show's holiday break, using the word PresidentDonald Trump made famous. And it wasn't the only rough language used on the show Saturday night.

"The book 'Fire and Fury,' a salacious expose of the Trump White House, was released last week," Jost said to start the segment. "And then this week, the sequel wrote itself."

The first story of Jost and Michael Che's "Weekend Update" segment kicked off by discussing Trump's comments this week on Haiti and African countries.

Jost's graphic for the story censored Trump's phrase as "s—hole."

"During an Oval Office meeting on Thursday, Trump attacked protections for immigrants from African countries, which he called s-holes. That's what NBC asked us to say, by the way. S-holes. Even though the president can say ..." and he continued on by saying the word.

"Oops," Jost said.

"At this point, I feel bad for parents of young children," Jost continued. "Everything you yell at them for, they can be like, 'But the president gets to do it.' The most insane thing, of course, is that Trump said a bunch of racist stuff right before Martin Luther King Day, which is like pounding beers in the car on the way to rehab. Now I'm worried about what he's going the say the day before Passover.

Jost also brought up Trump's further comments, in which he asked people in the Oval Office why the U.S. wasn't getting more European immigrants.

"Trump said, 'Instead, we should take more immigrants from countries like Norway," Jost said. "And Norwegians were like, 'America? We're not going to that shaather hoeven.'"

Jost wasn't the only one to get bleeped during the early part of "Weekend Update" — Michael Che continued the segment about Trump's comments, and used the president's words on air as well.

"You know, if I'm being honest, when someone asks me, 'Did you hear what Donald Trump said about Haiti and Africa?' I was like, 'Oh, boy. Did it start with an "N"?'" Che said. "But then I heard what it was. And I was like, that's it? I've said that about countries for not having a CVS.

"Here's the thing," Che continued. "My job is to make jokes about the news. But Trump saying something racist isn't exactly news anymore. It'd be news if Trump said, 'You know what we need more of in this country? Haitians.' And by the way, he's not the only one that thinks like that. I've lived in this country my entire life and I've been asked to go back to Africa several times. And it's never been because they thought I would enjoy it there."

Earlier in the show, host Sam Rockwell dropped his first f-bomb during a live sketch.

The sketch, about a local access-style science show and coming 10 minutes into the show, was actually Rockwell's first sketch after his opening monologue in which he basked in the glow of being a big deal after having spent most of his career as "that other guy" in movies.

The sketch in question saw Rockwell hosting alongside a pair of teenagers, played by "SNL" cast members Cecily Strong and Mikey Day. The joke in the sketch was that the kids were extremely dumb and unable to follow the rudimentary science experiments Rockwell was doing, which led to some demonstrable frustration on the part of Rockwell's character.

The experiment that inspired the f-bomb involved pouring vegetable oil into a glass of water and seeing what happened.

"Now watch the oil. Not that oil, Josh," Rockwell said when Day's character stared at the bottle of vegetable oil rather than the glass of water he had just mixed oil into. "The oil I just poured into the water. The oil is?

"False?" Day said.

"This isn't a true or false," Rockwell replied.

"True," Strong chimed in.

"You can't be this f—in' stupid," Rockwell then said, pausing and covering his mouth after uttering the f-word before continuing on.

Day and Strong improvised a solid reaction to the slip, looking like shocked kids whose teacher just said the f-word in class. Day put on an exaggerated shocked expression, while Strong plugged her ears.

While the curse was broadcast with no censorship in the New York broadcast, the f-bomb was censored in Los Angeles. That makes sense, given that "SNL" was broadcast live on both coasts — on the West Coast the slip occurred at 8:49 p.m.
