Howard Stern and Jimmy Fallon danced along to the “Hokey Pokey” song live from a Times Square billboard during Wednesday’s “Tonight Show”.

Stern was on the show to talk about his brand new book, Howard Stern Comes Again, when Fallon insisted he wanted to do something “big” to help him promote the release.

“How nice is this?” Stern said as Fallon cut to Times Square, before adding: “People of earth, how are you?”

He then got everybody singing along to the “Hokey Pokey” as the band played the music in the studio.

Stern’s interview also saw him poke fun at Fallon’s book Your Baby’s First Word Will Be DADA, as well as saying how it inspired him to write his first release in more than 20 years.
