Once again, the emcee-in-chief drops the mic.

President Obama kept a straight face during an appearance on Jimmy Fallon's "Slow Jamming The News” on Thursday night’s Tonight Show.

Obama and the host were backed by house band The Roots as they concocted an R&B song discussing the president's tenure in the Oval Office.

“We were able to stimulate the economy and get our country back on track,” Obama said.

Fallon replied in tongue-in-cheek fashion: “Oh yeah, President Obama stimulated long-term growth in both the public and the private sector.”

Roots frontman Tariq “Black Thought” Trotter sang about the president’s recent endorsement of Hillary Clinton in the tune.

“He created tons of jobs for you and me and he’s got one more left for Hillary,” he sang.

Obama also took a swipe at Donald Trump in the bit where he declared, "orange is not the new black," as to who will be his successor.

The president kept a straight face through the whole process while Fallon, the comedian, tried his best not to burst out laughing.

At the end of the seven-minute song, Obama dropped the mic just as he did at the recent White House Correspondents' Dinner.

Prior to The Tonight Show's episode airing, Trump and Hillary Clinton got into a down-and-dirty Twitter battle.

Trump tweeted Thursday: "Obama just endorsed crooked Hillary."

Within minutes, Clinton responded: "Delete your account."

Trump shot back: "How long did it take your staff of 823 people to think that up  and where are your 33,000 emails that you deleted?"

Republican National Committee Chairman Reince Priebus also weighed in on the Twitter beef, saying, "@hillaryclinton if anyone knows how to use a delete key, it's you."

Following Obama's endorsement of his former Secretary of State, Priebus tweeted: “I don’t think there’s been a candidate for this office more unethical and untrustworthy than Hillary Clinton.”

Massachusetts Senator Elizabeth Warren also ramped up her attacks on Trump, following her own endorsement of Clinton.

She called him a “thin-skinned fraud” and a “thin-skinned racist bully” in a speech Thursday afternoon.
