Jimmy Fallon debuted a mash-up of NBC’s Nightly News anchor Brian Williams rapping to “Rapper’s Delight" by The Sugarhill Gang on the Tonight Show on Wednesday.

Also involved in the clip is Lester Holt and Today Show co-anchor Kathie Lee Gifford, who makes a surprise cameo.

Daily News reports Williams is currently covering the Olympics in Sochi, Russia, and hasn’t responded to the hilarious segment yet.

Fallon has been doing well since moving from Late Night to the Tonight Show, starting this week.

As we previously reported, Fallon had the First Lady, Michelle Obama on the show on Thursday night. She was involved in his skit “Ew!” with Will Ferrell, which he brought with him from Late Night.

She also talked about Obamacare, saying “A lot of young people think they’re invincible,” adding, “But they truth is young people are knuckleheads. They’re the ones who are cooking for the first time and slice their finger open. They’re dancing on the bar stool.”

The show has brought in 7.4 million viewers on only its second night on Tuesday.
