If you thought Jimmy Fallon was going to assume hosting duties for “The Tonight Show” and leave behind his wacky ways from “Late Night,” you thought wrong. Fallon had friend Kristen Wiig appear in an interview as One Direction member Harry Styles on Tuesday (Feb. 18) and then Wednesday, he put together another video of “NBC Nightly News” anchor Brian Williams “rapping.”

Fallon’s industrious editors have previously made Williams “rap” the songs “Regulate” and “Nuthing But a G Thang.” This time around, the call is “Rapper’s Delight,” complete with help from fellow newsman Lester Holt and a cameo by morning-show host Kathie Lee Gifford.

The shenanigans continue below, when Fallon plays charades with his guests, actors Emma Thompson and Bradley Cooper and country music star Tim McGraw — and everybody is spectacularly bad at it, though we’re impressed Thompson knows “The Vampire Diaries.”
