All James Corden wanted for Christmas was to sing his favorite Mariah Carey holiday song with his idol, so he did. But on Thursday, the Late Late Show host also roped Lady Gaga, Elton John, Selena Gomez, Adele and a bunch of others into his all-star sing-along.
It all started out innocently enough, with Corden cruising around with Carey while the always-enthusiastic host thanking her for helping with his holiday shopping. "What would be the best gift? What would you want for Christmas?" he asked the singer. "I don't know ... I don't want to ask for something that's too expensive," she said. "Go on, put it out there," Corden encouraged.
"I want you to sing my song, 'All I Want for Christmas is You,'" she said. Corden didn't miss a beat, busting into the seasonal classic for a duet that morphed into verses with pretty much everyone who has done "Carpool" this year, including Demi Lovato, Gwen Stefani, Coldplay's Chris Martin, Nick Jonas and the Red Hot Chili Peppers. It was epic.
Late-night hosts took this week as an opportunity to look back on 2016, a year that according to James Corden was "kind of the worst." Colbert did it through song, while Corden chose a rapid-fire monologue.
Colbert, Michael Stipe and James Franco got together on Thursday's Late Show to remake R.E.M.'s "It's the End of the World as We Know It (And I Feel Fine)" as a eulogy for a rough 12 months.
Here are some of the not-great things Colbert ran down in his year in review (while Stipe chose to stand mute and roll his eyes): Zika, Harambe, the N.C. bathroom bill, the fall of Fox News' Roger Ailes, climate change, the rise of the alt-right, Melania Trump's plagiarism, the deaths of Prince, David Bowie and Leonard Cohen and, oh yeah, Trump, lots of Trump. Near the end Franco shows up to lend some harmonies and Stipe finally gives in and sings the chorus.
James Corden wrapped up Thursday's show by rattling off the events that occurred over the year and reiterating that 2016 was "kind of the worst."
"Britain left Europe which upsets me because I'm British, Angelina left Brad, which upsets me because I'm human," said Corden, adding that Netflix had chill but the FBI had "zero chill." He called Anthony Weiner gross, said "Ew" to Roger Ailes, mocked Kanye West for saying he will run for president, and said that above all, Putin is "actually the worst."
Then Corden became more serious and sincere. "As much fun as it is to joke about 2016 being the worst because of pop culture or Donald Trump or Kanye West, I really feel like we need to recognize that it's been particularly terrible for many, many people who are overseas."
The Late Late Show host was referring to the crisis in Aleppo, which he pointed out does not get a lot of news coverage in the U.S. and "we rarely are brave enough to talk about things like that on this show" but he wanted to shine a spotlight on the atrocities, suggesting viewers help by giving money to organizations committed to helping the children of Aleppo.
Trevor Noah was at his most serious Monday night with President Barack Obama, a semi-regular visitor to The Daily Show in past years.
Noah and Obama opened by talking about recent accusations of Russian interference in the election, which the President observed had been a part of the national debate for at least a month before the final votes were cast, but not often were people focusing on its implications. "These emails got a lot more attention than any policy," Obama said of the Podesta emails hacked and released on WikiLeaks, calling the information contained therein "routine." "Going forward, I worry that we won't spend enough time on self-reflection on how our democracy's working," Obama said.
Noah pushed Obama on President-elect Trump's contention that he doesn't require intelligence briefings, which also got a measured answer. "I think the president-elect may say one thing and do another once he's here," Obama said, noting that "It doesn't matter how smart you are," without intelligence briefings "you are flying blind."
Regarding future plans, Obama promised, "I think it is important for me to recharge. I think it's important for me to reflect. It's important for me to get back in my wife's good graces."
He said, "I don't anticipate that I suddenly just vanish, but I think it's important to give the incoming administration some space," but he added that in the case of certain violations — he mentioned a Muslim Registry in particular — he wouldn't remain silent.
Corden told him that every time they've met, Mars "seems like he's in a great mood," which he attributes to the performer's soft silk shirts and impressive hat collection. They tried out a few new looks, with the late-night host finally settling on a gold glittery cap that made him feel like "I'm just a guy who's constantly waiting for his Tinder date to turn up."
Mars told Corden he knew he wanted to be a performer at the age of 4, when he impersonated Elvis onstage, which led to a duet of the legend's "Jailhouse Rock." The singer gave Corden some dance tips, including "shoulder moves" that took a while to master, before teaching the host his best poker face from his card-shark days.
The duo sang their own versions of "Locked Out of Heaven," "24K Magic," "If I Knew," "Uptown Funk," "Perm" and "Grenade."
Fallon started off immediately with his Schwarzenegger impression, which impressed the action star. "There is no one that does my accent better than you," he told the host. "If I want to sound like me, I imitate you."
On Apprentice, Schwarzenegger said people will be "very surprised" when it returns Jan. 2. Fallon had some ideas for the host's new catchphrase to replace Trump's famous "You're fired," including "Hasta la vista, baby" and "You won't be back." The idea that made both laugh? "You're fired: Get to the choppa!"
Later, they participated in the show's "Snapchat Interviews," in which Fallon and Schwarzenegger answered questions on certain topics through the app's filters. "I'm having a great time with this, can we do this all night?" asked Schwarzenegger, laughing at each filter Fallon chose for him.
